Interview sheets you can track here
Blind 75 Tracker
Anyone with four to eight weeks before interviews who already knows the basics of arrays, recursion and hash maps.
NeetCode 150 Tracker
The default choice if you have two to four months. It is Blind 75 plus the gaps that Blind 75 leaves, especially tries, heaps and advanced graphs.
Which DSA sheet should you actually follow?
Most people pick a sheet by popularity and then quit somewhere around dynamic programming. The sheet is rarely the problem. The mismatch between how long the sheet takes and how long you actually have is the problem, so start from your deadline and work backwards.
Under two months. Do Blind 75. It is 75 problems that cover the patterns interviewers reuse constantly: two pointers, sliding window, binary search on the answer, graph traversal, and the handful of dynamic programming shapes that keep showing up. At two to three problems a day it fits in about four weeks, which leaves room to revise instead of cramming.
Two to four months. Do NeetCode 150. It is Blind 75 plus the gaps Blind 75 leaves open, mainly tries, heaps and the harder graph work. The ordering is also gentler: each topic starts with a problem you can solve, which matters more for finishing than most people expect.
Four months or more, starting near zero. Neither of the sheets above teaches you the fundamentals, they assume them. Work through a full curriculum sheet such as Striver A2Z, or a free learning path first, then come back and use Blind 75 as revision.
One rule that survives every sheet: a problem you looked up the answer to is not solved. Mark it for revision, come back in three days, and solve it without the editorial. The revision queue in each tracker exists for exactly that.
Other sheets worth knowing about
These are other people's curricula, so we link to the originals rather than rehosting them. The comparison is ours, the sheets are theirs.
Striver's A2Z DSA Sheet
about 455 problems, 18 stepsRaj Vikramaditya (takeuforward)
The most complete free curriculum in this list and the usual answer for Indian campus placements. It teaches from zero, so it is long. Budget four to six months.

Topic-wise and broad, weighted toward GeeksforGeeks problems. Good coverage, weaker ordering: it does not tell you what to do first.

Paired with their video course, so it is the friendliest start if you are learning the concepts and practising at the same time.

Do I need an account to track my progress?
No. Progress is saved in your own browser using local storage, so the tracker works signed out and offline. Nothing is uploaded. Use the export button if you want to move progress to another device or browser.
Which sheet should I actually pick?
If interviews are four to eight weeks away, do Blind 75. If you have two to four months, do NeetCode 150, which is Blind 75 plus the gaps it leaves. If you are starting from close to zero and have four months or more, work through a full curriculum sheet such as Striver A2Z instead.
Will I lose my progress if I clear my browser data?
Yes. Local storage is cleared along with site data, and it does not follow you to another browser or device. Export your progress to a JSON file first if that matters to you, then import it wherever you continue.
How many problems per day is realistic?
Two to three medium problems a day is a sustainable pace for most people with a job or classes. At that rate Blind 75 takes about four weeks and NeetCode 150 about eight. Doing ten in one day and none for a week is how people stall.
Is solving a sheet enough to pass interviews?
It covers the pattern recognition half. The other half is talking through your approach out loud, handling follow-up questions, and writing code that compiles under time pressure. Mock interviews cover that, sheets do not.
