With this score and rank in JEE Mains I'm sorry to say there are very slim chances of getting the college that you have mentioned above and for the advance there are chances but they are very less.
It will be better to wait for the result and then think about it.
For the college that you will get with your rank you can follow the link in the end of the answer.

You can buy the old used books in book stores. It will be offered at a lower cost may be half of the original rate. You can also buy book online through the shopping websites which always offer books at a lower rate. Not only IIT JEE books but also the other books will be offered at a lower cost than the original cost.

If you score well in JEE Advance then you can try for IITs. No doubt IITs are best. If your score in JEE Mains is good and average (150~240) then you can try for good NITs and IIITs. If your score is less than 150 then you can go for private colleges like Thapar, LPU ,CGC-Landran or try for BITS-Pilani, SRM and VIT-Vellore.

Hello Saurabh,
In this college, admissions are normally based on MHTCET. However, some seats against All India Quota are filled by JEE Mains ranking. But your ranking is really low and I fear you have only a slim chance.

No, at first you have to clear your compartment exam then you can take provisional admission in some college.
