DILR Roadmap, week by week
Your DILR plan around the daily 4:30-7:30 block. DILR is pure pattern-recognition + nerve, built by solving many varied sets and reviewing the key insight each time. Target: 96-99%ile.
Your 4:30-7:30 block, split
4:30-6:00 · New sets
3-4 fresh sets of the week's type from Logical Reasoning / Data Interpretation. Solve each fully, then check.
6:00-7:00 · Insight review
For each set, write the one key insight that unlocked it and "could I have seen it faster?", this is your insight library, the real asset.
7:00-7:30 · Speed reps
Re-do an earlier set you found hard, now against the clock, turn "solved" into "solved fast".
Train the exit, not just the entry
From day one, practise abandoning a set at the 10-minute mark if it isn't cracking. The hardest DILR skill is letting go, rehearse it in every session so it's automatic on exam day.
Phase 1 · Learn every set type , Jun 19 → Aug 31
One family per week (or two), untimed → timed. Goal: recognise every common structure and know its standard attack.
| Weeks | Set family | Source |
|---|---|---|
| 1 | Linear & Circular Arrangements | LR |
| 2 | Distribution & Grouping (people → attributes) | LR |
| 3 | Selection / Conditionals & Binary logic | LR |
| 4 | Ordering / Ranking · Networks & Routes | LR |
| 5 | Games, Tournaments & Scheduling | LR |
| 6 | Tables & multi-table reasoning | DI |
| 7 | Bar / Line / Pie + % change & growth | DI |
| 8 | Caselets (text → structure) | DI |
| 9 | Venn-based DI · Data Sufficiency | DI |
| 10 | DI + logic-twist hybrids (modern CAT favourite) | Both |
| 11 | Mixed review, all types, sets from past papers | Both |
End of Phase 1 checkpoint
You've seen and solved every common set type at least a dozen times. You can name a set's structure on sight, that recognition is what makes selection fast in Phase 2.
Phase 2 · Selection & speed , Sep 1 → Oct 31
The weekly loop2 DILR sections / week
Daily
4-6 mixed-type sets (no longer one type/day, randomise, like the real exam). Keep the insight library growing.
2×/wk
Full 40-min, 5-set DILR section. Practise the two-pass method: first 3 min rate all 5 E/M/H, then solve the 2 easiest fully before a third.
After each
Review selection, not just solutions: did you pick the right 3 sets? Most lost DILR marks are bad picks, not missing skill.
The selection drill
Once a week, take 5 fresh sets and only rank them E/M/H in 3 minutes, then check which were actually easiest by solving. This trains the single most important DILR instinct.
Phase 3 · Peak & Taper , Nov
- 2-3 full DILR sections/week at the real slot time, full conditions.
- Re-read your insight library, by now it's your edge; you'll recognise most set shapes instantly.
- Drill the 10-minute abandon ceiling until it's reflex.
- Last 3-4 days: a couple of easy confidence sets only; rest the mind.

DILR targets by month
| By end of | DILR mock %ile aim | "On track" |
|---|---|---|
| August | 70-85 | Recognise all set types |
| September | 85-93 | 2 clean sets reliably |
| October | 93-97 | 3 clean sets; selection sharp |
| November | 96-99 | 3+ sets, calm under time |
The great differentiator
DILR percentiles run low, so gains here move your overall the most. Three clean sets ≈ 96-99%ile. See the Score Blueprint and the DILR strategy.
