Affordable, Personalized, Self-Paced Test Prep & Math Help

Students achieve their academic goals; you achieve your financial goals

Invest in Caddell Prep Inc.

"A recent study found that 63% of high school seniors were not college ready*. Students need help outside of the classroom, but the cost of traditional tutoring and test prep excludes a lot of students. Also, many niche tests lack adequate test prep resources since many companies ignore those tests. That's why we offer affordable, personalized, self-paced test prep for those niche tests and the big market tests.

We believe that with the right tools and resources, all students can excel. It's our goal to provide students with the support they need to excel."

-Glyn Caddell, Founder and CEO

Caddell Prep can help students achieve more.  Caddell Prep provides personalized, self-paced tutorials and test prep to increase educational opportunities for students across the country. Our math tutorials are offered for free, while access to our test prep is priced affordably, starting at $79.

We believe online, self-paced test prep is better for students than in-person classes. The in-person model is extremely inefficient. It is virtually impossible for an instructor to teach at the pace of each student individually. Some students are able to progress more quickly than others, while some students need to review material longer before moving on. That's why we believe an online, self-paced option is actually a better alternative to in-person prep classes.

Plan for Rapid Growth

To help students at a larger scale, we’ve packaged our free math tutorials and practice problems as free homework teachers can use with their students. In addition, we’ve created a platform for schools to use our test prep with their students.

We will focus on sales to schools to rapidly grow market share, while helping many students at the same time. 

My Story

"I started tutoring in 2006 after graduating with my degree in mechanical engineering from NJIT.

While working as a mechanical engineer for a firm in NYC, I was used to working on multiple jobs, sometimes up to eight, at the same time. Then it seemed every week that the workload was becoming less and less. At lunch one day, I said to my manager that I think we will be laid off soon. It turned out that I was right. About a third of the company was let go the very next day. 

It was a blessing in disguise.

I started tutoring more, eventually full-time, and then opened up a tutoring center. I consider myself to be lucky for being being laid off at the beginning of the recession in 2008. I really do believe I was lucky because I truly love what I am doing now. I was able to grow to a team of 8 tutors and administrators, and spun-off this new company to help students at scale. 

I hope you will be part of the journey to help even more students."

- Glyn Caddell, CEO

- Students can practice at home and according to their schedules.

- Lessons are broken down into short videos followed by one or more questions

Not Your Typical Test Prep Company

Most Companies are Focused on the Big Name Tests with Their Online Test Prep, but There's a Huge Opportunity with Niche Tests

Technology for a Smart Approach to Test Prep

Bite-Sized Videos

Our lessons are broken up into short videos, normally less than 3 minutes. Each video is followed by one or more questions to keep students engaged and help them retain the information they just learned.

Optimized for Maximum Test Scores

Our test prep courses are designed to steer students in the right direction to maximize their scores, based on their results and the typical number of questions for each topic that appear on a test.

Practically Unlimited Questions

For one of our test prep courses, we were able to create a practically unlimited test bank of math questions with text explanations using computer science, which we will expand to all tests. We say practically unlimited because for many question-types we are able to generate over 10,000 questions, so we don't expect any student to run out of practice questions. 


Unlike other test prep platforms, students can use our math resources for help during the school year for free. This gives us a more in-depth look into students' strengths and weaknesses.

Sales to Two Groups that Support Each Other

We are in the online test prep market, but we operate in two different markets in that specific one. For each of the two specific markets, we have differentiators that separate us from the crowd.

Consumer Market (Parents & Students): 

Our biggest differentiator is our focus. While most of the companies focus on big name tests such as SAT, ACT and GMAT, we focus our attention on the small market tests that are just as important as the others. The benefit is that there is less competition. We might compete in small market tests, but all of the small markets add up to a large market that we have internally valued at $3.55 billion*. Plus, we believe that students who use us for tests early in their school careers will use us for the big market tests later on also. 

*Our internal market valuation is based on the following information.

  • There are approximately 52,463,000 students in USA from grades 3-12 (Source). 
  • If 98% were to choose a one-month option for $79, 1% were to choose a three-month option for $149, and 1% were to choose a one-year option for $189, the total value would be $4.72 billion. 
  • Considering 83.8% of the population has an internet subscription at home (Source) , the serviceable market value is $3.55 billion. 

Business to Business (Schools and Organizations): 

Many businesses try to develop relationships with schools and organizations, so they can push their products onto the students. We have taken a different approach. Many schools receive funding to help students get test grades up. However, schools don't want to train their staff to teach for specific tests. We provide all of the content including lessons, practice problems, explanations, and sample tests, then give access to monitor all of the work to teachers.

Parents and students can sign up for test prep and math help on their own.

Schools and teachers are able to use our test prep courses and math homework with their students.

Testimonials from Parents:

“I was looking for a convenient and low stress way for my daughter to prepare for the TACHS exam. In general, I found your program to be excellent. The lesson videos were great reviews, and the practice questions were very helpful. My daughter could work at her own pace and on her own schedule. She received a $5,000 scholarship to her first choice school, and was admitted to all three schools she applied to, which was exactly what we had hoped for. Thank you!” 

- Jean Kearns

“I just wanted to give you some feedback on your site. My son really liked using it. He said he liked the structure of the practice questions and the fact that he could work at his own pace. I just wanted a little refresher for him and this was perfect. His scores increased 70 points with your site's support! We are all very pleased. Thank you and good luck with your ventures. I have already recommended the site to several people.” 

- Jo Ann Hotaling

We launched a platform for schools to offer our test prep. After conducting market research by talking directly with tutors and administrators who are in charge of test prep in their schools/organizations, we built a product that met all of their need:

  • Teacher is able to monitor students individually
  • Teacher is able to monitor progress of the entire class
  • Teacher can see a breakdown of scores for each question to quickly know what to review
  • Students can move at their own pace
  • Students get personalized feedback based on their performance

Testimonial from an SHSAT Tutoring Supervisor:

"It's an excellent stand-alone tutoring program, in addition to one that you can use with teachers." - Barry Levine 

We Help Students in Many Ways

We Want to be the First Name that Comes to Mind When People Think About Education

Our Self-Paced Test Prep

Our Test Prep Courses are easy to navigate and guide students toward maximizing their scores. From the main course page, students can readily see what is left to complete and how they've done so far.

Lessons are short and captivating. Students are tested on what they've learned right after watching a short video.

  • Students progress is tracked whenever they take a sample test, complete a lesson, and answer practice questions
  • Tests are broken down into very specific topics to pinpoint students' strengths and weaknesses
  • Test have been analyzed to determine the most common topics
  • Students are guided to work on topics that offer the greatest room for improving their scores based on their proficiency and the typical number of questions that appear for each topic
  • Unlimited test questions. Using computer science we have have created an almost unlimited number of practice problems for one course, and we are updating the rest of the courses too.

Web Based-Math HW

We've packaged our free math practice into a platform that lets teachers use our practice problems as homework. 

  • Teacher's assign homework to their students
  • Student attempt homework
  • If a student can't answer a question, he can immediately see a video explanation before moving on to the next question
  • Homework is automatically graded
  • Reports are easily generated to see scores over a certain time period (such as a semester)
  • Teachers can see how the class did on a question-by-question basis
  • Teachers can see how each individual student performed

Math Lessons & Practice

We offer our math lessons and practice problems free for everyone to use. We currently have math lessons available for Pre-Algebra, Algebra 1, Geometry, and Algebra 2.

  • Math lessons are visible to member and non-members
  • Free math lessons serve as a marketing tool since we rank highly in Google for many math topics
  • Students must register for a free account to get access to our free math practice problems
  • When students register, they fill out a questionnaire that gives us insight into what tests they'll need to prepare for in the future

Helping Students Around the World

Our free math resources have been used by students across the country and in 21 other countries.

  • Test prep focus is initially USA
  • The global market presents a huge opportunity
  • We are able to start building brand recognition with our free resources before we launch paid courses internationally

Our Market and Industry

The K-12 test prep market was valued at $8.29 billion in 2016. The online test prep market is growing at an average annual rate of 6.11%. We have seen a drastic positive shift in consumers' sentiment toward online test prep. We believe the online test prep market will continue to grow a larger share of the overall K-12 segment.

Research from technavio shows growth in the global test prep market from a value of $24.57 billion in 2016 to $32.13 billion in 2021.

We are active in the K-12 test prep market with products for consumers and for schools and organizations.

As a part of the global edtech market, we believe it is important that the industry is expanding annually.

According to, the global edtech market is expected to grow 17% annually and reach a market value of $252 billion by 2020

Math is the same around the world, so it would be relatively easy for us to adapt our existing platform and expand globally when we are ready. Much of the content we have created will carry over to other markets.

Minimum Goal Reached! It's on!

almost 2 years ago

We have passed our minimum fundraising goal! This is extremely exciting news for us and our investors.

If anyone has been on the fence about investing because you were unsure if the campaign would happen or not, you don't have to worry about anymore. You can confidently invest today.

Thank you to everyone who invested so far, everyone who helped spread the word, and everyone who supported us to this point.

We look forward to working with everyone and providing help and test prep to all students, especially those taking niche tests that don't currently have great options and those who can't afford a private tutor or an expensive prep class.

Students Using Our Test Prep at School

almost 2 years ago

This is why we do what we do. 

All of the hard work is to help students.

These students attend test prep at their school, using our online course, every Saturday.

The instructors are able to use our platform to track the work the students do to identify their strengths and weaknesses and to make sure everyone is staying on track.

Students shown above are watching one of our lessons together as a group.

After the lesson, students worked through our practice questions at their own pace.

Students Drastically Improved with Our Online Test Prep

almost 2 years ago

Students who used our online test prep to prepare for the 2018 SHSAT had huge increases from the diagnostic test to the third practice test.

The test is broken down into two main sections: English and Math.

  • English: 24.8% increase in the number of correct answers
  • Math: 19.3% increase in the number of correct answers

Each section on the test has 57 questions. 

Comparing the last test the students took with their diagnostic test, our students ended up with, on average, 6.8 more questions correct on English and 7 more questions correct on math. The reason the percent increase is less for math than English but the average number of questions improved is higher for math than English is that, on average, the students started with a higher number of math questions correct than English questions correct.

Overall, we are incredibly happy with the results and look forward to helping even more students improve.

New Article: Designing accessible ed tech can be costly, but demand is on the rise

almost 2 years ago

At Caddell Prep, we do our due diligence to make sure our product is a fit for students.

First, we are experienced tutors. We work with students all the time, so we know what they need. We also have come across other platforms students have used and learned what students like and don't like about the ones they use.

Second, we are proactive in receiving feedback from students and teachers who use our product to learn what features they need. This includes reaching out to existing users and speaking with students and teachers who don't already use our product.

Third, our interns are high school students and their opinions matter. As students, they have the best insight into what students find valuable. One example is an intern suggested letting teachers see how the class performed on a question by question basis to identify specific homework questions to review because reviewing all questions during class wastes time.

The photo above was taken after speaking with a class of students about test prep.

Launched on StartEngine!

almost 2 years ago

We are excited to announce the start of our fundraising campaign on StartEngine to help our company move forward and help even more students.

Most of all, we are excited for the opportunity to work with and grow our community of investors. To us, investors are more than just a means to grow funds. Investors are a source of insight and connections into the education/edtech industry and potential ambassadors of our product to customers.

We are really excited about the next 3 months of this campaign, but also to the many years ahead of working together!
