Priyansh Agarwal
Curated by Priyansh Agarwal, ICPC World Finalist and AIR 1 in Google Kick Start, this sheet features all essential 1700 -rated Codeforces questions. With a Master (India Rank 34) on Codeforces and 4000+ students taught, Priyansh’s expertise ensures that this sheet will help you sharpen your competitive programming skills and make steady progress.
1700 on Codeforces is Expert level. Experts who clear Div. 2 C in most rounds and want Div. 2 D in most rounds.
What these problems lean on: DP with optimisation, Trees and DFS order, Number theory, Segment tree basics, Interactive problems.
The usual wall at 1700: Implementations get long enough that bugs, not ideas, cost the problem. Segment trees and interactive problems also start to appear.
How to practise it: Keep a tested segment tree and modular-arithmetic template. When you get WA, write a brute force and stress test it rather than re-reading your code.

1700 problems need longer, more careful implementations and more tree and number theory. 1600 is mostly about combining two familiar ideas; 1700 adds the data structures to make them fast.
Well above what most placement rounds ask. A 1700 Codeforces rating is a strong signal on a resume for product companies and competitive hiring.
There is no PDF here, and you do not need one. All 31 problems are listed in full on this page, free and without an account — and unlike a PDF the list remembers what you have ticked off, so you are not re-reading a static file to work out where you stopped. Use your browser's print view if you want it on paper.
Tick a problem on this page and it stays ticked. Progress saves in your browser straight away with no account, and the counts update per section so you can see which parts of 1700: CP-31 Sheet you have actually covered. Signing in with Google syncs it across devices.
At roughly 25 minutes a problem — reading it, solving it and writing the approach down — 31 problems is about 13 hours, or 1 weeks at ten hours a week. Treat that as a planning figure rather than a promise; the first pass through an unfamiliar topic is always slower.
Yes, completely, and no account is needed. There is no paid tier and nothing is held back — the sheet itself is by Priyansh Agarwal, and this is a free tracker for it.
Finish one. Sheets overlap heavily, so working several in parallel mostly means re-solving the same problems while never completing a full topic sweep. If you are not sure this is the right one for the time you have, the sheet comparison page puts the options side by side with hour estimates.
