What people say

We were very pleased with my son's SAT results. He was able to improve his score significantly. The smaller class sizes and individual attention at Caddell Prep is very beneficial to the students and leads to good results. I would definitely recommend Caddell Prep to others.

I took the class with 5 other students, and received very individualized attention. I was never hesitant to ask or answer questions, even when there was the possibility that I was wrong, because I was so comfortable in the environment provided by our teacher. I learned countless tricks to conserve time, manage the hardest questions, and take the test efficiently. My score ultimately increased by 250 points, surpassing my goal. I always recommend Caddell Prep to underclassmen looking for SAT classes!

Personally, I really enjoyed the lessons. Glyn explained things in a way that made it very easy to understand. I never got lost and if I had trouble completely understanding something Glyn would help me break it down. He also taught me a lot of important tips to keep in mind while taking the SAT.

Caddell Prep has always given my son the extra help he needed to build his confidence and help him succeed in his math classes. Glyn and his staff helped him focus on the math problems, break them down, and really understand the concepts needed to get the answer correct. My son also comes out after a session happy, relaxed, & not frustrated because he learned new techniques to tackle these math problems head on.

We were very pleased with Caddell Prep and the instruction they provided to help my children prepare for the TACHS Exam, which is the Test For Acceptance to Catholic High School. Both my son and daughter received scholarships at the High Schools that they wanted to attend. The small class size and Glyn's attention to detail were so important in their test preparation. Glyn most importantly improved their test taking strategy and confidence. I highly recommend Cadell Prep!

Testimonial from the Director of a Community Based Organization (CBO)

“They truly care about helping the students
Since the implementation of the online service, our students have voiced their appreciation of it, and our educators have informed us that it was very easy to track their students’ performance.
As a parent, as an educator, and as a professional in education, I recommend Caddell Prep because not only are their services very easy, user friendly, but at the same time, they truly care about helping the students gain better academic outcomes.”

Ready to Excel in School and on Tests?

Caddell Prep specializes in tutoring and test prep for subjects and tests that students take from grades 3 through high school, including Regents exams, high school entrance exams and college admissions. We have many ways to help parents and students prepare for tests and keep up in school including tutoring, prep classes, and online test prep.

Caddell Prep was founded by Glyn J Caddell, a graduate of NJIT (BS Mechanical Engineering) and of Staten Island Technical High School, which he is currently the alumni association president of. After working in engineering as a project manager for a data center and then as an HVAC design engineer in NYC, Glyn switched paths and founded his education company. It has been his goal to help students understand math as well as he does by making understandable connections between real life and math concepts and by building on previous concepts. When it coms to test prep, Glyn has brought an engineer’s approach. He started by analyzing all of the past tests available and categorizing the questions into different topics and developing lessons to maximize test scores based on the questions that actually appear on the test.

SAT Prep

Students typically take the SAT, which is administered by the College Board, in spring of junior year and in fall of senior year. However, some students take it even earlier, such as I in fall of junior year. When is the best time for you to take the test? Well, very simply, it’s when you have the most time to prepare for the SAT. SAT prep can take a month or more than a year. It really just depends on how much improvement you need to get the score you want.

SHSAT Prep

The SHSAT is the high school admissions test used for admission to New York City Specialized High Schools (except LaGuardia). The test is three hours long and covers English and math. Students typically start SHSAT Prep in the summer before 8^th grade. Some student start years in advance; while, other students only spend a month preparing. To determine how much time you would need, we advise taking a practice test and seeing how you score on it. Then compare your score tot the cut-off scores for the most recent SHSAT.

TACHS Prep

Most Catholic High Schools in NYC require students took the TACHS (Test for Admission to Catholic High Schools) as part of their application. Schools use TACHS scores similar to the way colleges use the SAT or ACT. The TACHS makes up a part of their criteria for acceptance, placement into programs (scholars, honors, etc.) and awarding of scholarships. TACHS Prep is important because a lot is on the line. Not only can the TACHS determine if you’ll get into a school, but if you’ll get scholarship money and placed into appropriate classes. Most students start preparing during the summer before 8^th grade.

Regents Prep

Students typically take Regents exams in June each year after taking the class in school. Regents exams are also offered in August and January for some tests, mostly for retakes. There are even schools that try to cover some subjects in half a year, so students have their first attempt in January and then cover another subject the second half of the year (spring semester) and take that Regents in June. Regents prep is typically started a month or more before the actual Regents. Some students may still be learning new material in class at that time, but prep can begin to review material learned earlier in the year since the tests are cumulative.

Online Tutoring

For online tutoring, we use a combination of tools including Zoom and a digital whiteboard that allows us to simultaneously work on problems and lessons together and share notes. Because of the coronavirus, all of our students had to switch to online tutoring. Surprisingly, many of the parents and actually prefer the virtual sessions to in-person sessions. It saves parents and kids time from having to travel to and from sessions. It is much easier to fit tutoring into schedules, and all of the students notes remain centrally located on their digital whiteboard for easy reference.
