GATE 2027: How to Use the Last 100-Odd Days with Free Resources Only

If you are reading this in late October 2026, GATE 2027 is roughly three and a half to four months away. GATE is usually held in the first half of February, though you should confirm the exact dates in the official brochure from the organizing IIT. That is enough time to make a real difference to your score, but not enough time to learn the whole syllabus from scratch at a comfortable pace. The students who do well from here are the ones who stop collecting resources and start triaging.

This post is about doing that with free material only: NPTEL, free YouTube lectures, previous year questions (PYQs) and free mock tests.

Step one: an honest audit (one evening)

Open the official syllabus for your paper and list every subject. Next to each, write one of three labels:

• Strong:** you have studied it and can solve most PYQs.
• Partial:** you have watched lectures but struggle with questions.
• Not started.**

Then look at the last five or six years of papers for your branch and note roughly how many marks each subject contributed. You are not looking for a precise formula, just which subjects reliably carry weight and which are small.

This one evening decides the rest of your preparation. Without it, most people spend November rewatching subjects they already know because it feels comfortable.

Step two: allocate time by return, not by comfort

The rough priority order is:

1. Partial subjects with high weight. These give the best return: you already have the foundation, you just need practice.
2. Not-started subjects with high weight. Learn the core, exam-relevant parts only.
3. General Aptitude and Engineering Mathematics. Together they are a big share of the paper, and aptitude in particular rewards steady practice.
4. Strong subjects. Maintain with PYQs, do not relearn.
5. Not-started subjects with low weight. Consider skipping them or doing only the most-asked topics. This is a legitimate strategy at this stage.

The plan in four phases

Phase 1, late October to end of November: close the gaps. Spend about 70 percent of your study time on Partial and high-weight Not-started subjects. Use the fastest free source you understand. For CS, that might be Gate Smashers or Neso Academy; for Civil, Mechanical or Electrical, free GATE playlists from coaching channels or the relevant NPTEL courses. Watch at 1.25x or 1.5x, and stop watching as soon as you can attempt PYQs on the topic. The remaining 30 percent goes to aptitude and maths, a little every day.

Phase 2, December: PYQs subject by subject. Solve every PYQ for each subject from the last ten or so years. For CS, GATE Overflow has them organized by topic with discussions. For other branches, official past papers are available from the GATE websites of the organizing IITs, and several free platforms compile them topic-wise. Do not read the solution until you have genuinely tried.

Phase 3, January: full mocks and the error log. Take a full-length mock or a past paper two or three times a week, in exam conditions, using the virtual calculator. Spend at least as long reviewing each mock as you spent taking it. Several platforms run free mock tests close to the exam; use them alongside past papers.

Phase 4, the final 10 to 14 days: revision only. No new topics. Formula sheets, your error log, flashcards and one or two final mocks for timing.

The error log is the most important document you own

For every question you get wrong, in PYQs or mocks, write down:

• The subject and topic.
• Why you got it wrong: concept gap, formula forgotten, calculation slip, misread question, or time pressure.
• Where to fix it: a page in your notes or a timestamp in a lecture.

After two weeks of this, patterns appear. Many students discover that a large share of their lost marks come from misreading questions or calculation slips rather than not knowing the concept. Those are much cheaper to fix than learning a new subject.

Make revision active

Rereading notes and rewatching lectures feel productive but do little in the final months. Replace them with:

• Self-testing:** close the notes and write down a derivation or formula from memory, then check.
• Flashcards with spaced repetition** for formulas, standard results and definitions. A few minutes every day beats a long session on the weekend.
• Short quizzes** at the end of each lecture you watch, so you know immediately whether it stuck.

If you are working through several NPTEL or YouTube playlists at once, it helps to track them in one place. Filow turns each playlist into a course with progress tracking, timestamped notes, and quizzes and flashcards per lecture, which makes the "where was I, and what did I mark to revisit" problem go away.

What to stop doing

• Collecting resources.** You do not need a fifth playlist on thermodynamics. You need to solve the PYQs.
• Long Telegram and YouTube comment debates about cutoffs.** They change nothing you control.
• Studying 14 hours on Sunday and 2 hours on Monday.** Consistency beats bursts, and burnout in January is common.
• Skipping aptitude because it feels easy.** Easy marks you drop are still marks.

If you are a working professional or in final year

You may have only two to three hours on weekdays. In that case, compress Phase 1, lean more heavily on PYQs, and protect weekend mornings for full mocks from December onward. Accepting that you will skip a low-weight subject or two is not giving up; it is how you score well with limited time.

The next hundred days will go quickly. Decide on your plan this week, write it down, and spend your energy executing it instead of re-planning every Sunday.
