What resources and YouTube channels are best for CAT DILR practice?
2IIM and Rodha are the two channels that consistently produce high DILR scorers, but the honest truth is that no single resource substitutes for solving 30-50 timed sets per week in the three months before CAT. Resource selection matters far less than volume and discipline.
YouTube Channels, Ranked by Use Case
Different channels serve different learning stages. Here is how they actually compare:
| Channel | Best For | Teaching Style |
|---|---|---|
| 2IIM (Rajesh Balasubramanian) | Understanding the "why" behind set logic | Detailed, first-principles |
| Rodha (Ravi Handa) | First exposure to new set types | Clean, fast-paced walkthroughs |
| Unacademy CAT (Patrick Dsouza, Aditya Singh) | Technique refinement at intermediate level | Structured, lecture-format |
| CATKing | Variety across older CAT patterns | Broad coverage, some dated content |
Start with Rodha to understand a new set type quickly, then revisit the same concept on 2IIM when you want the deeper reasoning. That two-pass method works well for arrangement sets, distribution puzzles, and games-and-tournaments, which are the three patterns CAT tests most heavily.
Platforms for Timed Practice
Free question banks from Cracku and 2IIM are genuinely solid for topic-wise drilling. Cracku's mock series costs roughly ₹1,000-1,500 for a full package, and the post-mock analytics (set-wise time, attempt rate) are worth that price alone. IMS, TIME, and Career Launcher all offer credible full-length mocks; pick one series and stay consistent rather than jumping between all three. Using five different mock platforms simultaneously fragments your performance data.
Official IIM-released papers from CAT 2017 onwards are non-negotiable. They are free, and solving all of them under timed conditions gives you a direct benchmark against actual difficulty levels.
The 2019 and 2021 papers had particularly tricky reasoning-heavy sets that are excellent calibration tools.
How to Structure Weekly Practice
DILR is a pattern-recognition skill, not a content subject. You build it through repetition, not memorization.
- Solve 4-6 sets daily, timed at 8-10 minutes each, in the core preparation phase
- Track set types: if you are avoiding games-and-tournaments or network diagrams, those gaps will cost you on exam day
- Review every rejected set post-practice to train your triage instinct
The Skill Nobody Mentions
Your DILR percentile is decided in the first 30-40 seconds of each set, not during solving. High scorers at 99+ percentile consistently say their edge was learning to reject a set fast, commit resources to winnable ones, and not chase sunk-cost sets.
That judgment is only built through timed practice under real pressure.
This is genuinely hard to develop. Most people practice correctly but never time themselves honestly. A set that takes you 18 minutes in untimed practice will almost certainly fail under exam conditions. Build the discipline early.
In the actual CAT DILR section, you have 40 minutes for roughly 4-5 sets. Attempting 3 sets cleanly with 90%+ accuracy outperforms attempting all 5 sets with scattered errors. Structure your practice around that reality from day one.
Pro Tip: Every Sunday, solve one full DILR section from a past CAT paper under strict 40-minute exam conditions, then spend 30 minutes reviewing every set you did not attempt, including why you rejected it.
