GATE — Last 45 Days
February (typically first or second weekend of February)
45 days before GATE CS is sufficient to move from rank 5,000 to rank 1,000 if used correctly. GATE is predictable — the same 8–10 topic areas appear every year, and 30% of questions are directly similar to previous year questions. The strategy is simple: master the predictable, ace the familiar.
45-Day Phase Plan
Phase 1: Topic Coverage Audit + PYQ Baseline
Day 1–15
- Attempt 1 full GATE CS mock to establish your baseline score and identify weak topics
- List all 10 core CS topics and rate yourself: Strong / Needs revision / Weak
- Prioritize by marks: Algorithms (15%), Programming & DS (15%), DBMS (11%), COA (10%), OS (9%)
- GA (General Aptitude): spend 3 days on this — 15 marks, extremely predictable format
Phase 2: Systematic Topic Revision + Mock Cycle
Day 16–35
- Cycle through all core CS topics: 2 days per topic, PYQ from 2019–2024 per topic
- Full mock every 5 days with 2-hour post-mock analysis
- Engineering Mathematics: spend 4 days — Linear Algebra, Probability, Calculus, Discrete Math
- Marks-per-hour optimization: move from weak topics to strong topics by day 35
Phase 3: Speed & Accuracy
Day 36–42
- All full mocks now in 3-hour strict conditions — no calculator for Programming questions
- NAT (Numerical Answer Type) practice: attempt all NAT questions from 2019–2024 PYQ
- Finalize skip strategy: which topics to leave blank vs attempt with 50% confidence
- GA preparation: 5 days of Aptitude + Verbal — these 15 marks are near-free at this stage
Phase 4: Rest & Confidence
Day 43–45
- Light review of formula sheets and CS concept summaries only
- No new topics, no new mocks
- Sleep 8 hours each night
- Review your best-performing mock to build confidence

Subject-wise Strategy
Algorithms + Data Structures (30% of marks)
CriticalTime complexity analysis, sorting algorithms, graph algorithms (BFS/DFS/Dijkstra/Bellman-Ford), dynamic programming. Solve all GATE PYQ on these topics — repetition across years is very high.
Avoid: Don't waste time on advanced data structures (B-trees, Fibonacci heaps) — GATE CS tests classic DS only.
DBMS + OS + COA (30% of marks)
HighDBMS: SQL queries, normalization (1NF–BCNF), ER diagrams, transaction management. OS: scheduling algorithms, deadlock, virtual memory, page replacement. COA: pipeline hazards, cache mapping, instruction set.
Avoid: Don't go into OS or DBMS implementation details — GATE tests theoretical concepts and numerical applications.
Engineering Mathematics + GA (30% of marks)
HighMaths: focus on Linear Algebra (rank, eigenvalues), Probability (Bayes theorem, distributions), Discrete Math (graph theory, combinatorics, logic). GA: Verbal Ability (reading comprehension, grammar) + Numerical Ability (percentages, averages, simple equations) — 95% predictable format.
Avoid: Don't underinvest in GA thinking it's too simple — 15 marks at 95% accuracy vs core CS questions at 60% accuracy makes GA the highest-efficiency block.
Theory of Computation + Compiler Design (10% of marks)
MediumTOC: DFA/NFA constructions, CFL pumping lemma, Turing machines (decidability). Compiler: parsing (LL/LR), code generation basics. These are 10–12 marks — attempt only confident questions in the exam.
Avoid: Don't spend more than 4 days total on TOC + Compiler if you haven't covered them — the marks ROI is lower than Algorithms or DBMS.
✓ Do This
- Complete all GATE CS PYQ from 2015–2024 — approximately 1000 questions. This is the most valuable dataset
- 45-minute to 3-hour mock ratio: 6–8 full mocks in 45 days, all with post-analysis
- GATE score depends heavily on NAT questions — attempt all of them (no negative marking)
- Build a formula/concept sheet for each topic: one page per subject, updated every 5 days
- GA preparation: do not skip. 15 marks at 90%+ accuracy is achievable with 1 week of dedicated GA practice
✗ Avoid This
- Don't attempt questions you have no confidence on — GATE MCQs have −1/3 or −2/3 negative marking
- Don't cover new CS topics after day 35 — if you haven't seen it, you can't revise it
- Don't skip Engineering Mathematics — it's 13–15 marks and the most formula-driven, hence most improvable quickly
- Don't rely on coaching institute mock scores alone — old GATE PYQ is the most accurate difficulty calibration
Last-Week Checklist — tick every item before exam day
Common Mistakes in the Final Phase
Spending equal time on all CS topics regardless of marks weightage
Impact: Spending 3 days on Compiler Design (5%) vs 3 days on Algorithms (15%) is a 3× efficiency loss
Fix: Allocate time proportional to marks: Algorithms+DS (30%): 14 days. DBMS+OS+COA (30%): 12 days. EM+GA (30%): 8 days. Others (10%): 4 days.
Attempting all MCQ questions even with no confidence
Impact: GATE MCQs have −1/3 (1-mark) and −2/3 (2-mark) negative marking. At 100 total marks, random guessing on 20 unknown questions costs you 6–10 marks net.
Fix: Develop a confident-attempt threshold: only attempt MCQ if you can narrow down to 2 options AND have directional confidence. NAT questions: always attempt.
Not solving 2019–2024 PYQ under timed conditions
Impact: GATE repeats question types. Candidates who know all PYQ solve them 30% faster in the actual exam.
Fix: Solve every PYQ from 2019–2024 as a timed 3-minute exercise. If you can't solve in 3 minutes, flag for revision.
Underestimating General Aptitude preparation
Impact: GA is 15 marks — equivalent to 7–8 core CS questions. Most candidates score 8–10/15. With 1 week of dedicated prep, you can consistently score 13–14/15.
Fix: Dedicate 5–7 days to GA: Verbal (reading comprehension, sentence completion), Numerical (percentages, averages, ratios). All from GATE PYQ format.
Frequently Asked Questions
I'm at GATE Score 550 in mocks. Can I reach 700 in 45 days?
A 150-point GATE Score jump in 45 days is achievable but requires identifying exactly which topics are pulling your score down. At Score 550 (~rank 5,000–7,000), you're likely scoring 50–55 raw marks. Getting to 700 requires 65–70 raw marks — a 15-mark improvement on a 100-mark paper. This typically means fixing 3–4 specific topic areas that are contributing systematic errors.
Should I attempt all 65 GATE questions or be selective?
Be selective on MCQs, aggressive on NATs. NAT questions (approximately 15–20 questions, 35–40% of marks) have zero negative marking — attempt every single one. For MCQs, skip any question where you can't narrow down to 2 options. A GATE score of 700 can be achieved by answering only 50 questions correctly if they are the right 50.
How much time should I spend on GA in the last 45 days?
5–7 days total for GA. This is the highest-ROI investment in your 45-day window. GA is 15 marks; after 1 week of practice, most candidates consistently score 12–14/15. At GATE's difficulty level, this is equivalent to solving 6–7 core CS questions correctly.
I have 45 days but haven't covered COA (Computer Organisation). What should I do?
COA is approximately 9–10% of GATE CS marks (9–10 marks). In 45 days, you can cover the essential COA for GATE in 3 days: CPU organization, pipeline stages and hazards, cache memory (mapping, replacement), and basic I/O. Focus on PYQ from 2019–2024 for COA — the question types are highly repetitive.
