Is this the right course?
Yes, if your student is taking the Upper Level ISEE
That's students applying to grades 9–12. Every lesson and every practice set is pitched at this level.
Probably, for the Middle Level
The strategies carry over completely. The practice questions are harder than what a Middle Level student will see, which is fine for strong students and frustrating for others.
Not yet, for the Lower Level
Younger students need a different course. Join the newsletter and you'll hear when there is one.
Give it four to six weeks
Twenty to thirty minutes every couple of days beats a three-hour cram the weekend before. The one thing this course can't fix is starting the night before the test.
Built like the test
Each lesson video is built to match the section it covers, so your student practices the pacing while they learn the strategy. Every practice question comes with full reasoning, not just a correct answer. The first lesson is free to watch, so you can see exactly how I teach before you buy.
From parents and students
“Prepared! That's how my middle schoolers both felt after taking Tim Ricchuiti's ISEE Prep course. Tim understands the minds that created the test, so each lesson offers insider information on how to take it. The videos are engaging and to the point; every minute packs a punch. Truly, I can't imagine sending my child into the ISEE without this preparation.”
“Tim Ricchuiti helped my daughter with ISEE preparation, and she was well prepared in taking this test. My daughter applied to one of the most competitive private schools in Dallas and was accepted, thanks to the scores she received on her ISEE.”
“Mr. Ricchuiti has an amazing way of making difficult material engaging and accessible, even for 14-year-old boys! As a mom, I find myself watching over their shoulders wishing I had a teacher like him when I was in school.”
“Working through practice tests with his guidance helped my confidence grow, and that preparation proved invaluable on exam day. Whether an ISEE, an ACT, or an SAT is in your near future, I highly recommend Mr. Ricchuiti's online courses.”
“As a former test-prep instructor and a highly skilled educator, he's intimately familiar with test-mastering skills and time management. Our two boys have worked with him on ISEE and SAT preparation. Experienced, knowledgeable, and fun, whether one-on-one or in a group.”
“Tim Ricchuiti was able to help prepare my children for the ISEE and the ACT with patience, kindness, and focus. He has a remarkable way of explaining difficult material that makes sense to his students. They were extremely pleased with their test results.”
Who's teaching
Too often, standardized tests are treated as measures of ability: if you're good at them, you're smart and capable; if you're not, maybe you're just not cut out for it. I don't believe those are real categories. Students can become much better at these tests with the right instruction: instruction that builds understanding, reveals connections, and teaches students how to think through unfamiliar problems rather than simply memorize procedures.
I spent ten years teaching test prep for a national company and the years since teaching mathematics in a private school. This course brings those experiences together. It is the same thoughtful, concept-driven instruction I give the students in front of me, recorded so yours can benefit from it, too.

Questions parents ask
How long should my child plan to prepare?
Four to six weeks, depending on comfort with the material. Consistent practice wins: 20 to 30 minutes every couple of days produces more progress than three or four hours once a week.
Are practice tests included?
For diagnostic practice tests there is only one source I recommend: the test maker itself (ERB, now E3n), at iseetest.org. The course includes practice sets for every technique it teaches, with full explanations. It does not include full-length official tests.
Does it suit different skill levels?
Yes. Students work through the videos and practice at their own pace. The course is designed for the Upper Level ISEE (students applying to 9th grade and above); Middle Level students will still get a lot from the strategies.
How often can my child take the ISEE?
Up to three times in twelve months, once in each testing season: fall (August to November), winter (December to March), and spring/summer (April to July). My advice is to plan on one sitting and sign up for a second only if the score and the target are far apart.
How does the course help with time management?
Two ways. Each lesson video is built to match the section it covers, so stamina builds as students work alongside the videos. And the quant and verbal lessons teach explicit pacing strategies for each section.
What does my child need?
A device with internet access and a quiet place to focus. Practice questions, lesson content and PDFs are all included.
Where does the course live?
Checkout and lessons are on our course platform at courses.polymathematic.net. You'll create a login there; your student can watch on any device.
What if it isn't a fit?
Watch the first two lessons. If it's not right for your student, email me within 7 days of purchase and I'll refund it in full.
