Logical Prep is the adaptive online ISEE prep platform built by Central Park Tutors — finding your child's exact gaps, building skills week by week, and tracking real progress toward test day. Not a generic course. A personal tutor that never sleeps.
Built by the extraordinary team of teachers at Central Park Tutors — featured in the New York Times, hired by Columbia Teachers College to teach test-prep, and drawing on more than twenty years of experience working hand in hand with families from more than fifty of the most demanding private schools in NYC and boarding schools around the country.
Every student starts with a diagnostic. Everything after that is personalized.
Save the heartache of wasted time, the anxiety of not knowing if you are covering the right material or whether you're progressing at the right schedule. With detailed lessons delivered responsively to your child's progress, Logical Prep is light-years beyond what other platforms offer: it's more thorough and more detailed, while saving you and your child time and anxiety.
A 25-minute adaptive diagnostic tests all four ISEE sections. It adapts in real time — finding your child’s exact strengths and gaps. No prep needed.
→ Instant results with a predicted ISEE stanine score
A personalized study plan is built instantly — week by week, calibrated to your test date. Each skill has a narrated video lesson followed by adaptive practice. Skills are taught in priority order: biggest gaps first.
→ 128 video lessons · AI hints on every question
Timed mastery challenges confirm your child can perform under real exam pressure — not just get it right eventually. Full-length practice tests simulate the real ISEE with section timers, essay, and a detailed predicted score report that updates your study plan.
→ 6 full practice tests · Predicted stanine after each one
When your child gets a question wrong, most test prep just marks it incorrect and moves on. Logical Prep does what a great tutor does — it asks a follow-up question to find out why.
Do they understand fractions but struggle to multiply them? Or do they not yet understand what a fraction is? The answer changes everything about what to teach next.
If a building block is missing, Logical Prep pauses, teaches that foundation first, then returns to the harder skill. No time wasted. No guessing.
Each of the 128 skill modules includes a narrated whiteboard video and clearly laid out lesson.
Only the lessons your child needs to learn are included in their study plan. Your child's time is valuable — we treasure it, and teach what they need to know.
Most ISEE vocab prep is just flashcards. Logical Prep teaches words through their Latin and Greek roots — so one root unlocks 5–8 words at once, and gives your child a tool to decode words they've never seen before.
The parent overview gives you a clear, jargon-free picture of your child's progress — what they've mastered, what they're working on, and what's coming next.

All tutors are experienced, American, ISEE teachers with a Master's Degree, and years of teaching experience — with backgrounds not only in test-prep, but in the English and Math foundations that are critical for success. Your tutor sees your child's exact progress, error patterns, and study plan before the first session — so every minute is focused on what matters most.

Most test prep is static — the same content for every student. Logical Prep is genuinely adaptive at every layer.
Every question is chosen based on the student's current rung — not too easy, not too hard. Questions get harder as skills are confirmed, easier when errors appear.
AdaptiveEvery skill has a whiteboard-style video with a patient teacher voice. Students watch the problem get solved step by step before tackling practice questions.
Video lessonsWrong answers aren't just marked incorrect. The system identifies whether the error was conceptual, procedural, or careless — and adjusts future questions accordingly.
AdaptiveStuck on a question? The Help Me button generates a live AI walkthrough of that specific problem — step by step, tailored to the exact question on screen.
AdaptiveAfter every diagnostic and full test, students see a predicted scaled score, stanine (1–9), and percentile band — using ERB's exact scoring tables for their level and grade.
Score predictionKnowing the answer isn't enough if it takes 3 minutes. After regular mastery, students take a timed round — proving they can perform under exam conditions.
Timed masteryThree built-in games turn drilling into play: Blitz is a 90-second arcade round, Boss Battle is an untimed math duel against a boss, and Case File is a suspect chase for reading comprehension. Every round still feeds the same study plan and mastery tracking behind the scenes.
GamesEnter the test date and the study plan calculates exactly how many modules per week are needed to finish before exam day — automatically adjusting as sessions are completed.
PlanningSix complete ISEE simulations — two per level — with real section timers, between-section breaks, essay prompt, and a detailed score report with stanine prediction that feeds back into your study plan.
Full testsA dedicated overview tab shows section-by-section progress, this week's focus skills, and the predicted score — without the student-facing detail that can feel overwhelming.
For parentsA dedicated module teaches 10 proven ISEE test-taking strategies — from process of elimination to time management — with 30 practice problems that reinforce each technique before exam day.
StrategiesA full essay lesson teaches the five-paragraph ISEE structure, time management, and key strategies — with an annotated sample essay showing exactly what a strong response looks like.
Essay prepStudents write timed practice essays and receive instant AI feedback scored on four criteria: organization, support, voice, and mechanics — with specific notes on strengths and what to improve next.
AI gradingVocabulary taught through Latin and Greek roots — one root unlocks 5–8 related words. Integrated into the weekly study plan with spaced repetition that keeps words locked in long-term.
VocabAdd one-on-one tutoring with a tap. Every tutor is an experienced, American ISEE teacher with a Master's degree — and they see your child's exact progress, weak spots, and study plan before the first session.

Most students start 10–14 weeks before their test. Start now to stay on track.
Logical Prep is an adaptive online ISEE preparation platform built by Central Park Tutors, drawing on over 20 years of experience preparing students for New York City's most demanding private schools. It covers all three ISEE levels — Lower, Middle, and Upper — with 4,800+ adaptive practice questions, 128 narrated video lessons, two full-length practice tests, and a personalized study plan calibrated to each student's test date. With detailed lessons delivered responsively to your child's progress, Logical Prep is light-years beyond what other platforms offer: it's more thorough and more detailed, while saving you and your child time and anxiety.
Yes. Logical Prep covers ISEE Lower Level (for students applying to grades 5–6), Middle Level (grades 7–8), and Upper Level (grades 9–12). Each level has its own adaptive diagnostic, skill graph, lesson content, and predicted score reports based on ERB's official scoring tables for that grade level.
A traditional tutor meets once or twice a week and covers what they think the student needs. Logical Prep works every day, adapts to exactly what the student demonstrated in their last session, and never forgets a skill gap. It's not a replacement for a great tutor — it's what students do between sessions to maximize every hour of instruction.
Logical Prep costs $39 per week, billed weekly with no long-term commitment. Cancel anytime. Every week includes full access to the complete platform: adaptive diagnostic, personalized study plan, all 128 narrated video lessons, all skill modules with AI hints, essay prep with AI feedback, two full-length practice tests, and predicted ISEE score reports. A 7-day free trial is included — no credit card required.
