help

got 91.6%tile in jm , 116 in cet {marks} , 140 in iat {marks} didnt give any other exams (big mistake)
i need some advice please , in my mocks (2025 papers) i was getting 120 to 140 marks on avg , 154 was highest that isnt a lot but its hell a lot better than 85 in my actual paper , i fumbled in mains hard i couldve gotten more but thats in the past now.
i have decided on a drop
question 1
i never really prepped for advance ( had a local coaching they only taught cet) , now im starting from 16 june ( going on a family trip tomm) , so should i do advance level prep from now on?

question 2
in my area there isnt a good coaching and i dont want online like pw or allen ( no hate) , so some chapters are very conceptually weak , i considering watching lecs from mohit tyagi channel for them , any other suggestions?

question 3
my math is very weak , please any suggestions would help to improve it , any teacher i can follow or book , is starting cengage in drop year be okay?

question 4
in many ama , i saw toppers using sbt , irodov , pathfinder , i saw some questions in pdf and cant even comprehend how to solve them ,i did hcv and thoda sa dc pandey (scored 90 in phys in mocks)
so should i start solving them? like not all one book which is most relevant to jee

question 5
im thinking for quizzer droppers test series , i have heard they are good and i got the iat test series , analysis was goated , any other suggestions"?

question 6
i didnt solve like modules n all in my coaching only pyqs , and people are talking abt resonance , allen modules should i solve them , along w lecs ?

question 7
i dont need to watch every chapters lecs , i have short notes and long notes of every chp , but i neglected some very fundamental chps
units trigo
waves sets
magnetism complex no.
ac ckts circle
functions
pnc and probability
and some others

so like i need to do theory on these and some oc lec by ns sir on organic for advance,so like doing them to good level would be optimal in my drop yr , rt?

question 8
chem was my strongest suit but i got fucked in jan papers , mainly bio molecules and salt analysis fucks me the most , i did n awasthi and ms chouhan in 2 yrs but i made a grave mistake of seeing solutions like too early if im stuck for like 2 mins i opened the solution and msc has a lot of irrelevant questions got stuck in them , for drop year im thinking i will resolve ticked questions and pyqs mostly , anything you would like to suggest for chem?

question 9
how to not panic during mocks? , if you get a hard section of a subject , after that the whole mock goes to shit

question 10
anything you would like to suggest for drop year , would help

thank you sm bro
