Three weeks is enough for Ignite if you practise under the clock. The concepts are Class 10 level; the test is about answering 60 questions in 90 minutes without freezing. Here is a plan that has worked for science graduates who had not touched aptitude since school.
Three-week plan
- Week 1 — Concepts. Numerical: percentages, profit-loss, SI/CI, ratio, averages, time-work, number system — one topic a day with 15 problems each. Reasoning: series and coding-decoding. Verbal: the five grammar rules on the verbal page.
- Week 2 — Speed. Timed sets of 20 questions in 30 minutes for each section, daily. Add blood relations, directions, seating arrangements and syllogisms. Learn 10 new words a day from previous TCS papers.
- Week 3 — Full mocks + coding. One full 120-minute mock every second day using NQT foundation papers. On alternate days, write two of the standard programs from scratch in your chosen language and run them.
Test-day tactics
- Answer every question — there is no negative marking.
- Two passes per section: first pass for sure-shot questions (aim 12+), second pass for the rest, guessing whatever is left in the final minute.
- In verbal, do grammar and vocabulary before the reading passage.
- In reasoning, leave seating arrangements for last.
- Attempt the optional coding problem — even a partial, compiling attempt is noted; choose the language you will name in the interview.
Interview prep runs in parallel
Spend 20 minutes a day from week 1 on your project story and Java / DBMS basics — the interview follows the test by only a few weeks. The interview questions page has the full set.
Ignite is one route; keep the others open. Enter CodeVita if you enjoy programming, and keep an eye on Infosys, Wipro and Cognizant drives that also accept BCA / B.Sc — the aptitude preparation is identical.
