This discussion is mainly for the NSEs, including NSEP, NSEC, NSEJS, NSEB, NSEA held in India. However, anyone who wants to practice good Science questions, you are welcome!
The rules are:
Post problems related to Science
Don't post repeated problems(I mean if someone has posted it already, don't post again).
Past year problems are also welcome.
Don't post comments not related to any problem.
Don't write the answers in the comments.
If you are not posting a problem yourself, and find a good problem in the Community(old or new), please post it here.
If you learnt any new concept, do share it with us!
I request everyone to please share the links of the previous deleted discussion.
Let's together learn Science!
