The test is a tool.
Critical thinking is the point.

Every competitive admissions test is a proxy for a set of reasoning skills that will serve your child for life. Our program teaches those skills directly, through precision test preparation and a structured critical thinking curriculum, so your child can do well on the test and even better in the years that follow.

Scientific approach to test prep

Reverse-engineered from the source.

Most test prep is guesswork. Tutors and prep centers work from experience and intuition, not from a systematic analysis of what each test actually measures. We do the opposite. Every test on this platform is built by reading the official materials carefully and working backwards from the answer rationales, using test theory, cognitive science, and the principles of critical thinking. What you get is adaptive tests, an intuitive dashboard, and a precision error analysis that shows exactly where your child should focus next. Currently available for the SHSAT, with more tests in development.

Adaptive practice tests

Tests route the student to the next set of questions based on their performance, matching the real adaptive structure of the exams. Our scoring is conservative, so your child never thinks they're more prepared than they actually are.

Distractor trap analysis

Every wrong answer is tagged by the specific reasoning error behind it. After each test, your child sees which traps caught them and how often, so review is targeted, not random.

Accuracy by skill area

Broken down by section and skill so you know exactly which areas are costing the most points (and by how much) across every test your child has taken.

Built from official materials

Every question on this platform was written by reading the official test handbooks and working backwards from the answer rationales. Not guesswork, but a systematic reconstruction of what each test actually measures.

Critical Thinking Curriculum

Comprehensive method to teach your child critical thinking.

For families who want more than test readiness, we offer a structured program to prepare your child for the intellectual challenges of high school and beyond. The curriculum is built around five foundations of clear thinking: patterns, causality, uncertainty, models, and decision-making. Covers ages 8 to 16. One lesson per week, can be integrated alongside any existing curriculum. This is the same analytical rigour that drives our test preparation, built into a long-form curriculum that will last a lifetime.
