You have plenty of time my advice is to get lectures from etoosindia and dronstudy complete them and revise every illustration shown in them 5-6 times.Then get books which only have questions with explanations solve all the question 2-3 times.No one can stop you from AIR-1.
Get lectures of best only(My experience):
nv sir - EtoosIndia & Nitin Agrawal sir- dronsrudy
First, complete the dronstudy and them jump to nv sir as Nitin sir will build your basics and nv sir will take you to advance level
Mc sir-etoosindia(only these are required) watch all of them twice.
JH-sir and Nj sir both etoosindia.
mtg 36 years of question paper all 3 pcm
and vmc packets
If you do all the above told mark my words no one can even be near you in the competition of jee
