What free resources are recommended for each CAT section?
Free, high-quality CAT prep resources exist for every section, and you can build a complete stack without spending a rupee if you know exactly where to look. The three sections, VARC, DILR, and Quant, need different tools and different daily habits.
VARC: Reading Comprehension and Verbal Ability
Start with GMAT Club's free RC archive once you understand basic passage mapping. The forum explanations are often sharper than paid course material.
For grammar and para-jumbles, Pagalguy's VARC forum has curated question sets from past CAT papers with detailed community solutions.
Daily reading matters more than most aspirants admit. Twenty minutes of *The Economist* or *The Hindu* editorials every morning builds reading stamina faster than any drill.
Strong VARC scorers rarely treat reading as prep, they treat it as a habit. RC passages in CAT 2023 and 2024 leaned heavily on philosophy and social science, so read outside your comfort zone.
DILR: Puzzles and Data Interpretation
Aptitude Jab is the best free DILR resource available. It covers all major puzzle families including grids, tournaments, arrangements, Venn diagrams, and every DI variant you'll encounter.
Start at Level 1 and advance only when you're solving 3 out of 4 sets correctly. Jumping to hard sets too early builds bad habits, not speed.
CAT previous year papers from 2017 onwards are freely available on the official IIM CAT website and are genuinely irreplaceable for DILR. The section format has stabilized since 2017, so these papers are close simulations.
Skip niche types like timezone DI or complex network graphs unless you're already targeting 95+ percentile in this section.
Quant: Concepts to Problem Solving
| Resource | Best For | Cost |
|---|---|---|
| Rodha (YouTube) | Number systems, geometry, algebra fundamentals | Free |
| Arun Sharma books | Structured concept-to-advanced progression | Borrow or library |
| CAT PYQs (2015 onwards) | Real exam difficulty calibration | Free (official site) |
| Unacademy free lessons | Topic-specific concept gaps | Free tier available |
Rodha's YouTube channel is the strongest free option for concept building. The lessons on number systems and geometry are particularly clear. Once concepts are solid, solve PYQs from 2015 onwards, available in free PDF compilations on Telegram groups like "CAT Prep 2025." Quant has a significant amount of topic repetition across years, especially in arithmetic and algebra, so PYQs pull double duty as concept revision.
How to Combine These Without Burning Out
The mistake most aspirants make is treating these resources as a checklist. Depth matters more than breadth.
Spend 4-5 weeks per section before attempting mixed mocks, and time every practice set from day one. Untimed practice builds a false sense of competence that mocks will destroy.
- VARC: 20 min daily reading, 2-3 RC sets per day from GMAT Club
- DILR: 1 full set daily (timed at 20 minutes) from Aptitude Jab or PYQs
- Quant: 1 concept topic per day on Rodha, followed by 15-20 PYQs
Free resources are enough to crack 99 percentile if used with discipline. The tools are not the bottleneck. Consistency is.
Pro Tip: Every Sunday, solve one full DILR section from a CAT paper (2017-2024) under strict time conditions and review every wrong set before touching any new material that week.
