catprep: a 55-day CAT 2026 plan for the 95th percentile in VARC, DILR and QA

A static site for one goal: the 95th percentile in every CAT 2026 section. It turns four study guides into one 55-day plan, from 5 October to the exam on 29 November.

Section Target What's there
Today Day count, today's QA task, this week's VARC and DILR focus, admission deadlines
Plan The 7-phase chart with 12 mocks, daily routine, week-by-week checklist
QA 9 correct of 22 Toolkit, exam-day rules, 12 chapters of arithmetic and easy algebra, error log
VARC 12 correct of 24 Reading method, four passages, the four VA question types, practice set, error log
DILR 2.5 sets The 5-minute scan, one method for every set, 14 worked sets with practice, error log
Admissions 97th–98th overall Score-to-percentile calculator, IIM weightage and cutoffs, NIRF top 50, backup exams

Every worked example, passage, set and practice question comes from the guides and is original, written to mirror recurring CAT patterns; none is a past-paper question. Cutoffs and dates are as of 6 October 2026.

How it's built

  • Next.js 16 (App Router), every page prerendered; no database, no auth, no server code.
  • Tailwind CSS v4. Neo-brutalist light theme, with a dark theme revealed through a View Transition.
  • Content is data in src/content/ (qa.ts, varc.ts, dilr.ts, admissions.ts, plan.ts, logs.ts); pages render it.
  • Checklist ticks and the three error logs live in the browser's localStorage.
  • Formulas are rendered with KaTeX at build time.

Run it

pnpm install
pnpm dev     # http://localhost:3000
pnpm test    # plan date maths, percentile interpolation, and DI chart data against the guides' printed answers
pnpm build

Live at catprep-95.vercel.app. Social previews use that address; set NEXT_PUBLIC_SITE_URL to override it on another host. No other environment variables are needed.
