Yes, there were some people I know who became sincere only in last two- three months (yeah, they has some basics, but not much I promise) and cracked NEET but yeah, competition is getting fiercer, year by year so you need to work really hard.
You can do it only if you have some basics, like you’ve got some but have studied less the whole year ( like 2hrs a week). If you’re at zero, then you can only study biology from NCERT, solve and memorise the question bank for all subjects which would get you a rank that would not be considered ‘that bad’. But if you’re on the higher IQ side, you can end up finishing everything too but I’m talking about an average student here.
First go through the question bank to get an idea of what’s important and what is not. Usually, students are advised to first study thoroughly, solve exercises and then move to the question bank but that wouldn’t work when you have only 2 months in hand. In biology and organic chemistry you’ve to revise NCERT only, I hope you’ve covered it atleast twice or thrice before. There are some chapters which have some specific questions repeated almost every year, don’t miss them.
