How to use the Blind 75 Progress Tracker
- 1. Update statusesMark each problem as attempted, solved, or solved but worth revising, and jot down the approach.
- 2. FilterShow one topic, one level or one status to plan your next session.
- 3. See your reportGet solved counts by topic, your weakest topic and a finish date, plus a CSV of everything.
What the Blind 75 is
The Blind 75 is a well-known list of 75 problems, first shared on the Blind forum, chosen to cover the main patterns asked in coding interviews with as little repetition as possible. The tracker groups them as the original list does: Array (10), Binary (5), Dynamic Programming (11), Graph (8), Interval (5), Linked List (6), Matrix (4), String (10), Tree (14) and Heap (2). Merge k Sorted Lists appears under Linked List, so the heap section has the other two.
Difficulty labels are the ones the problems have on LeetCode at the time of writing; they can change.
Worked example
Say you've solved 20 problems, attempted 5 more, and plan 2 problems a day. The progress report shows 20 / 75 solved and estimates the remaining 55 will take 28 days, giving the date. It also names your weakest topic by share solved, such as a topic where you haven't solved anything yet, as the place to focus next. Marking a problem as "Solved – revise again" counts it as solved but keeps it on your revision list.
Using it well
- Solve problems by topic first, then mix them, so you learn to recognise patterns without the label.
- Write one line in the note for every problem: the pattern and the trick. Those notes are your revision sheet.
- Download the CSV from the report now and then; browser storage can be cleared.
Frequently asked questions
Are the problems linked?
No. Search the title on LeetCode or another practice site. The names match the usual list.
Does it sync between devices?
No. Progress is saved only in this browser. Use the CSV to keep a copy.
Is this the same as a DSA sheet?
It's a short, focused list. For a bigger sheet, use the DSA sheet tracker.
Is the Blind 75 tracker free?
Yes. Everything in the Blind 75 tracker works without signing up. The first time you ask for a result, we ask once for your name and WhatsApp number; after that the Blind 75 tracker and every other Uncodemy tool open straight away.
