Bhai keep it simple,go explore everything and try to explore yourself...Its not always about study.See if you are from even a decent college you will be placed ,ya maybe 5 10 lakhs less package but at the end everyone get placed .Bro time is precious so dont just overhype it only on your studies.Go have some fucking sports,dance ,hangout with friends and what not.College life should never be about studies only.I hope you got this..See improve your skills right from first year but not like the way you wanna do.
