good morning i passed jee main 2018 with 165 marks thinking to prepare for advance please give me tips

Congratulations you will get a good nit with these marks,now if we talk about jee advance try to focus on your best rather than working on the weak portion at this point of time,but you should be aware of all the formulaes of all chapters.Try to revise concepts of inorganic chemistry as well as organic chemisrty.
Once check jee main paper as well try to find mistakes you have done in that paper,not repeat them again.
Never waste time on a single question in jee advance paper because advance paper is for them who know how to leave the questions as you know cutoff is like 45% generally so you can leave at least 20-30% questions and attempt remaining 70-80% with good accuracy,this is the way of success
