Spent a few weeks parsing every CAT paper from 2020–2025 and mapping each QA question to its Arun Sharma chapter. Built a small tool on top of the data that estimates your QA + DILR percentile based on chapter-level self-rating.
Trying to figure out if this is actually useful or just an interesting exercise. Would appreciate honest reactions from people deep in CAT prep — does this answer a real question you have, or are existing predictors and mocks already doing the job?
The data isn't scraped from one source. Topic-level difficulty per slot was cross-referenced from credible sources (listed on the website), every question was hand-classified, and the scoring is a Monte Carlo simulation with 400 runs per slot — not a single number that pretends to be precise. Methodology is visible on the site.
It's non-commercial atp.
