Questions, answered.

No. Adam (the founder) has no engineering background and scored Q88. The Quant curriculum starts from first principles. The issue is almost never knowledge — it's strategy and systematic review.

The full curriculum is designed for a 16-week timeline at ~90 minutes/day, 5 days/week. You can compress to 8-10 weeks if needed, or extend if you have more time. Most students see meaningful score movement within 4-6 weeks.

Yes. Many students use Zakarian as the review-and-analytics layer on top of content-heavy courses. The error log, mock debrief tools, and adaptive plan work well as a second pass after finishing a content course.

Most courses are content libraries. Zakarian is a system. The error log turns mistakes into data; the analytics show patterns over time; the adaptive plan re-prioritises your week from your last seven days of misses; the coaching addresses root causes rather than re-teaching content. The whole product is built around the loop, not the lectures.

Yes. Every section, every chapter, the diagnostic, the scoring scale (205-805), and the section ordering all target the GMAT Focus Edition. The legacy GMAT was retired in early 2024; Focus is the only version offered now and the only one we prep for.

No. The signup form asks for your name, email, and a password. No payment details are collected until you decide to upgrade.

If you don't upgrade, your account simply becomes inactive — there's nothing to cancel and no charge. Your study data is retained for 30 days in case you want to come back. After 30 days of inactivity, the account is deleted per the privacy policy.

No. The public sampler at /free-diagnostic is 10 questions and gives you a per-section signal (Strong / Mixed / Needs work). The full diagnostic on the trial is 30 questions and produces a real readiness band on the 205-805 scale, plus a per-topic and per-difficulty heatmap that drives the adaptive study plan.

Yes — the 10-question public sampler is at /free-diagnostic. You can also share the result. The full 30-question diagnostic with the per-topic breakdown requires the free trial signup.

Most students see measurable improvement on mocks within 3-4 weeks of consistent daily practice. The biggest gains usually come between weeks 4 and 10, after the error log has enough data for patterns to surface.

The Intensive package includes a score guarantee. If you complete all 16 scheduled coaching sessions, follow the study plan consistently, complete all assigned mocks with debriefs, and don't hit your target score, you choose between a full refund or extended coaching at no cost. Full conditions are on the refund policy page.

We guarantee you'll hit your target score IF you complete the Intensive program as designed. We can't guarantee outcomes for students who skip sessions, don't follow the study plan, or change their target score mid-program. The guarantee is conditional and the conditions are clearly spelled out.

The two scales are not directly comparable — GMAC deliberately offset them. Roughly: Focus 705 ≈ Old 730, Focus 695 ≈ Old 720, Focus 645 ≈ Old 680. Use the score converter at /score-converter for any specific score.

Yes — the chapter index is non-linear. The diagnostic identifies your weakest topics; the adaptive plan recommends those chapters first. You can read any chapter in any order.

A weekly plan that re-prioritises based on your last seven days of practice data. If your error log shows your dominant tag has shifted from Conceptual to Time pressure, the next week's plan reflects that. Static schedules drift out of usefulness in two weeks; the adaptive plan adjusts.

The error log uses a six-tag taxonomy (Conceptual / Careless / Time pressure / Misread / Strategy / Other). Every miss gets exactly one tag. After 60-100 entries, the dominant tags surface — and those tags, not the topics, tell you what to drill. It's the loop the platform is built around.

Yes. Self-Study includes 3 mocks; Self-Study Plus includes 3; Coaching includes 5; Intensive includes unlimited. Each mock is a full-length 3-section simulation with a structured debrief tool.

Yes. The biggest myth is that Verbal is 'easier for native speakers.' The actual disadvantage is comprehension speed, not comprehension itself — and speed is fixable with the structural-skim approach. Non-native students who run the loop typically close 60-80% of the Verbal gap in 12 weeks.

Yes — Sentence Correction is gone from Focus. This was the section where native speakers had the biggest structural advantage, so its removal is a small but real boost for non-native speakers.

Different test, different skill — your IELTS or TOEFL score is not predictive of your GMAT Verbal score in either direction. If you need IELTS / TOEFL for admissions, take it; don't expect it to substitute for GMAT prep.

No. The tutor is for clarifying questions about specific problems, on-demand. A human coach is for reviewing your error log over time, identifying patterns the tutor can't, and adjusting your overall plan. The Coaching and Intensive packages include human coaching with Adam directly.

Yes — the spaced review queue and the offline drill runner work without internet. Visit /review online once to cache your queue + question payloads, then drill at /offline/drill on the plane / commute. Your attempts queue locally and sync when you're back online.

Yes. The platform is a PWA (Progressive Web App) — on iOS or Android, use 'Add to Home Screen' from your browser to get a standalone-app experience with offline support.

Self-Study and Self-Study Plus are lifetime access — there's nothing to cancel. Coaching packages run for the program duration; you retain platform access during and after the program. If you cancel before completing the program, refund terms apply per the refund policy.

Installment plans are available for the Coaching and Intensive packages. Email us to set up a 2-payment or 4-payment schedule.

Self-Study and Self-Study Plus include a 14-day money-back guarantee, no questions asked. Coaching is refundable in full before the first session and non-refundable after. Intensive is backed by the score guarantee — see /refund for the full conditions.
