The 100-Point Score Increase Guarantee

100 Points Can Mean the Difference Between Your Safety School and Your Dream College

100 Points Can Mean the Difference Between No Scholarship and a Full Scholarship

Complete the course, take the SAT, and if your score doesn’t increase 100 points, you get a refund.

Here is what that means specifically.

Your baseline is a real SAT score. It has to be an official SAT taken before starting the course. If a student hasn’t taken the SAT, a PSAT score counts as the starting point instead. If a student has taken neither, he isn’t eligible, because there’s nothing to measure the increase against.

Completing the course means finishing every lesson, the first set of practice questions for each lesson, and all 5 practice tests.

It does not mean finishing every set of practice questions. A student who masters a topic after one set shouldn’t have to grind through four more to stay eligible. The requirement is built around covering the material, not around logging hours.

Taking the SAT means an official College Board administration of the Digital SAT, within 60 days of finishing the course. If there’s no test date inside that window, the next available date counts.

The remedy is a refund of the $299.

We can offer this because the course is built around what actually appears on the test rather than around covering everything evenly. A student who finishes the lessons and takes all five practice tests normally improves by more than 100 points.

Why Students Struggle with the SAT

The SAT isn’t difficult because students aren’t smart. It’s difficult because it asks about familiar concepts in unfamiliar ways.

Students leave practice tests saying three things.

“I never learned this.”
“How was I supposed to know that?”
“I don’t understand why my answer is wrong.”

None of those means a student can’t improve. They mean the student needs better explanations.

That’s what this course is built around. Every explanation answers the questions students actually ask. Why does this work? Why doesn’t my answer work? What clue did I miss? How do I recognize this question type next time?

A student who understands the reasoning stops guessing. That’s where the score increase comes from.

Built by an Instructor, Not a Publisher

Most SAT courses are written by publishing companies. This one was built by the person who teaches the lessons.

Glyn Caddell has been tutoring New York City students since 2008 and founded Caddell Prep in 2012. He holds a BS in Mechanical Engineering from NJIT and wrote Digital SAT Math Secrets, which contains over 900 practice problems. He is a graduate of Staten Island Technical High School.

He built every lesson in this course himself, using an engineer’s approach: work out what the test actually asks, categorize it, and teach that.

The explanations come from thousands of hours of working through these questions with students who got them wrong and asked why. That’s why they answer the question a student is actually stuck on rather than the question a textbook expects him to ask.

Price	$299, one time

Lessons are built as short videos with practice questions between them, not as one long video. A student answers something every few minutes instead of watching for an hour.

That structure is deliberate. A student watching a long video normally believes he understands it. A student answering a question every few minutes finds out whether he does.

Every practice question is followed by a video explanation showing how to work through it. That’s the part most self-paced courses leave as written text.

The 32 Topics the Course Covers

The College Board sorts SAT math into four content domains and SAT Reading & Writing into four more. Those categories are too broad to study from. A student told he is weak in Algebra still doesn’t know what to work on.

We went through every practice test the College Board has released and categorized every question by what a student actually needs to know to answer it. That comes to 32 topics: 17 in math and 15 in Reading & Writing.

Then we measured how often each one appears. Linear functions is 15% of the math questions. Words in context is 16.5% of the Reading & Writing questions. Some topics show up on fewer than one question per test.

The course is built in that order. The lessons spend the most time on the topics carrying the most questions.

See the full breakdown of the 17 Digital SAT math topics and the 15 Digital SAT Reading & Writing topics, including how often each one is tested.

The Assessment: What to Study Next

The course tracks progress on each of the 32 topics as a student works through lessons, practice problems, and tests. After every practice test the assessment updates, and it shows which topics are costing the most points.

That list is the study plan. As a student improves, the list changes, because the topics with the most room for improvement change.

Here is how one student described it.

One part of the online SAT test prep that helped me the most was the Advanced SAT Assessment. After each practice test, I knew exactly what topics I had to study to increase my score. It helped me go from 1180 to 1410.

Maximizing a score doesn’t mean working on the weakest topics. It means working on the topics with the greatest room for improvement, and those are different things. A topic a student is weak in that appears on one question is worth less time than a topic he is slightly weak in that appears on eight.

Why This Instead of Free SAT Prep?

Khan Academy offers free SAT preparation built with the College Board. It’s good, and a disciplined student who works through it consistently will improve his score. Any honest comparison starts there.

Three things are different here.

Video explanations for every question. Khan Academy has video lessons and written explanations for practice questions. Every practice question in this course has a video explanation showing the work. For a student who got something wrong and doesn’t know why, watching someone work through it is different from reading about it.

A ranked topic list. Khan Academy adjusts the difficulty of what it gives you. This course tells you which of the 32 topics are costing you the most points and in what order to work on them.

Lessons ordered by frequency. Khan Academy covers the material evenly. This course spends the most time on the topics that carry the most questions, because we measured which ones those are.

If a student is disciplined and will work through free material on his own, free material is a reasonable choice. This course is for students who want the topics prioritized and want to see the work rather than read it.

Is the On-Demand Course Right for Your Student?

Self-paced prep works for a student who will open it without being told to. It doesn’t work for a student who needs someone expecting him on Wednesday.

That’s the honest test, and it matters more than anything about the content.

Who the Course Works Best For

Students balancing AP classes, sports, music, work, or other activities, whose schedules can’t accommodate a class meeting three times a week.

Students outside the New York area, since our classes and in-person tutoring are on Staten Island.

Students who want to start now rather than wait for the next class date.

Students who want to prepare for more than one SAT, since access doesn’t expire.

The course works less well for a student who needs accountability. A student who won’t open it on his own is better served by an SAT prep class, where the schedule does that work.

Start With a Free Diagnostic SAT

Before buying anything, it’s worth knowing where the points are going.

A free diagnostic SAT gives a student an accurate score based on College Board scoring, plus a breakdown of which of the 32 topics are costing him the most points. It also establishes the baseline the 100-point guarantee is measured against.

There’s no charge, and it can be taken online.

Student Results

My daughter is in SING and softball so she couldn’t fit a tutor or class in her schedule for SAT prep. We decided to use Caddell Prep Online SAT Course. She improved 180 points from doing the lessons and practice. She got a 1340 on the SAT. We are so happy!

Some days I would watch the videos during a free period and then do questions after soccer practice when I got home. The lessons are to the point and show you exactly how to do better. I was able to increase my score 210 points!

Caddell Prep has the best online SAT prep course. From the layout of the lessons to the easy to understand videos, this is the best.

On-Demand Compared With a Class or Tutoring

The course is $299. An SAT prep class is $1,299 for 24 hours of instruction in a class capped at eight students. SAT tutoring is $2,640 for 24 hours one-on-one.

The differences are cost, schedule, and whether someone is expecting the student to show up. The course covers the same 32 topics as the class. What it doesn’t provide is an instructor noticing when a student is lost.

Some students use both. Taking the class and keeping the course afterward for review is common, since course access doesn’t expire.

Frequently Asked Questions

How long do I have access to the course?

For every SAT you take while you’re in high school. There’s no subscription and no expiration.

How many times will I be charged?

Once. $299, one payment.

How does the refund policy work?

Finish every lesson, the first practice set for each lesson, and all 5 practice tests. Then take an official SAT within 60 days, or on the next available date if there isn’t one in that window. If your score hasn’t gone up 100 points from your previous SAT or PSAT, you get a refund. Full terms are above.

Can I watch the lessons in any order?

Yes. Students can work through the content in any order. We recommend following the order it’s presented in, since the lessons are sequenced by how often each topic is tested and by which concepts build on others.

Are all sections and topics covered?

Yes. All 17 math topics and all 15 Reading & Writing topics.

Can I access the course from my phone or tablet?

Yes. The course works on any device with a browser.

Do I need to buy anything else?

No. The lessons, practice questions, explanations, and practice tests are all included.

When should a student start preparing for the SAT?

It depends on the gap between the current score and the target score. Take a diagnostic test, compare the score to the target, and work backward from the test date. Students who need a 200-point gain should start earlier than students who need 50.
