Remember Words for Good, Not for the Exam

Every word comes back right before you'd forget it — Day 2, Day 7, Day 21. Each review resets memory to 100% and decays slower. That's the spacing effect.

Everything You Need to Know About WoahCab

WoahCab was created by Tanvir Touhid Alvi (Rank 2nd, IBA BBA 29th) and Iftekhar E Mahbub Zeeon (BUET). Tanvir personally experienced how traditional 1000-word rote memorization lists fail students right before competitive exams. He developed WoahCab using memory science, SM-2 spaced repetition, and relatable Banglish mnemonics after mastering 800 high-frequency words in just 7 days to crack IBA DU.
Unlike passive PDF word lists or generic flashcard apps, WoahCab is built specifically for Bangladeshi admission and competitive exam takers. It organizes 1000 high-frequency words into 40 bite-sized chunks, pairs each word with memory hooks & exam sentences, and uses active recall quizzes to lock vocabulary into your long-term memory.
Over 10,000+ students use WoahCab to turn 3 months of painful vocabulary cramming into 10-minute daily micro-sessions. Our SM-2 spaced repetition engine calculates exactly when your brain is about to forget a word and schedules it for review at the perfect interval.
Our 50-question diagnostic test evaluates your current English vocabulary level in 30 minutes, ranks you on the public leaderboard, and provides a customized study plan for IBA, BUP, GRE, or SAT preparation.
Yes! You can take the diagnostic test, explore initial word chunks, and access free exam prep guides without paying anything. Upgrading to a premium plan unlocks all 40 chunks, unlimited revisions, and speedrun quiz battles.
