GATE 2026 AIR 70 CSE Nikhil Chhillar’s Preparation Journey & Success

Achieving GATE 2026 AIR 70 CSE while balancing college is a feat of discipline and strategy. This breakdown of Nikhil Chhillar’s preparation journey reveals how he mastered the syllabus in just six months through intensive study and precise time management. By focusing on his approach to goal setting and overcoming the challenges of a Tier-3 college, aspiring candidates can gain actionable insights into the consistent effort required to secure a top-tier rank in the competitive GATE environment.

GATE Achievement Overview

Nikhil Chhillar, a third-year engineering student, achieved a remarkable feat by securing GATE 2026 AIR 70 CSE. This accomplishment was the result of approximately five to six months of highly dedicated preparation, balanced alongside his regular semester examinations and college attendance.

The table below provides a quick snapshot of his achievement and preparation profile:

Strategic Preparation and Goal Setting

Nikhil's motivation for GATE was driven by an aspiration for higher education at IITs or IISc, addressing concerns about placements from his Tier-3 college. Initially targeting a good rank in his fourth year, his goal evolved after early lecture exposure. He strategically decided to complete the entire syllabus in the third year to significantly reduce future pressure, aiming for an Under-500 rank. Remarkably, the entire GATE syllabus was completed within three to four months.

Study Discipline and Time Management

Nikhil maintained an intensive daily study regimen, averaging 10 hours of study per day, alongside 8 hours of college attendance. He gradually increased his study hours from 5-6 to 10 hours over a few weeks, preventing burnout through effective music breaks. Consistency was key; even during social events, preparation was never allowed to drop to zero. He emphasised maintaining some study, however minimal. When motivation for new topics waned, he would focus on revising previously completed courses rather than taking a complete break.

Effective Practice and Subject Mastery

Previous year questions (PYQs) were solved two to three times to solidify understanding. While C programming and data structures and algorithms (DSA) felt easier, subjects like computer networks (CN) and computer organisation and Architecture (COA) were initially challenging. However, through dedicated effort, Nikhil achieved 100% accuracy in these subjects in the actual GATE exam, marking them as rank-making courses. 

For difficult questions, he would re-read and revise underlying concepts, then repeatedly practice (2-3 times) similar questions. To enhance retention, he dedicated two hours to theory revision in the morning, immediately followed by solving practice questions on those topics.

Mock Test Approach and Analysis

Initial PYQ attempts typically showed 50-60% accuracy, which steadily improved. Subject-wise mock tests, taken as courses were completed, yielded around 70% accuracy. Full-length mock tests began in late December, with the first score being 45 marks. However, thorough analysis of mock tests was crucial, identifying numerous silly mistakes (around 20 questions in the first mock) and highlighting the need for increased concentration. His highest mock score was 73 marks, but he notes that (Memory Tip: Mock test scores reflect preparation, but are not necessarily predictive of the final GATE score. His actual GATE score was 77, exceeding his highest mock score). Additionally, 10 previous year's papers were treated as simulated mock tests, achieving up to 90 marks in easier papers.

Coping with Academic Interruptions and Distractions

To manage semester exams, Nikhil took 10-15 days off from GATE preparation, a strategy made possible by his proactively advanced syllabus completion. For digital distractions, his phone was kept silent and at a distance during study. While brief YouTube diversions (max 5 minutes) occurred, the key was his ability to quickly switch back to studies. As he puts it, (Memory Tip: 'Returning from distraction is an art' – highlighting the discipline to quickly refocus on academic tasks).

Role of Educational Platforms

Physics Wallah's "Khazana" resources were highly instrumental in clarifying concepts across all subjects, aiding understanding where it was previously lacking. Nikhil’s primary emphasis was on understanding theory, problem-solving, and retaining academic content, prioritizing core learning over extraneous details.

Key Learnings and Aspirant Advice

Nikhil advises that 10 months of serious preparation are generally sufficient for GATE. Starting early offers a significant advantage to first-year students, enabling a gradual pace of syllabus coverage, fostering better conceptual clarity, and easing the balance between college academics and skill development. The most crucial advice is to maintain unwavering consistency in preparation, as breaking consistency makes it extremely challenging to regain momentum. While intensive daily study is effective, strategic early starts allow for spreading out study hours, reducing burnout, and better accommodating personal events and semester exams.
