WHO WE ARE

About PEAK

Practice materials written by expert tutors, designed for student success.

A little history…

Our Story

We are a team of educators who have spent years guiding students into their dream schools. Recently, we noticed a disconnect: our ISEE students were still relying on paper practice, even though the actual test had moved online.

Frankly, we hated seeing families buy expensive, outdated materials that weren’t all that great. After working with these tests day in and day out, we knew we could write something better.

So, we built the testing platform we wanted for our own students.

No tedious grading. No guesswork. Just realistic practice that raises scores faster.

Developed by Tutors, Not Tech Bros

PEAK is an online testing platform developed by the team at Mulholland Prep. We aren’t tech bros—we are tutors, and have been our students’ trusted teammates for decades.

We started in 2005 with high quality, in-person, one-on-one tutoring. Over the last 20+ years, we’ve expanded our team and our services, providing in-person and virtual tutoring for all ages. Along the way we developed a treasure trove of high-quality academic practice materials to help our students succeed.

About the ISEE

The Independent School Entrance Exam (ISEE) is a standardized test used by private and independent schools for admissions decisions. The test assesses students’ reasoning and achievement across verbal reasoning, quantitative reasoning, reading comprehension, mathematics, and an essay section.

PEAK’s practice tests are carefully designed to match the structure, timing, and difficulty of the actual ISEE, giving students the most authentic preparation experience possible.
