JEE Advanced

Yes, you can get into one.

With this rank in JEE Advanced 2018, you can get a seat in IIT-Indore or IIT-Baroda or IIIT Raipur.

Prefer any coaching printed booklets or hend written notes, for reading and prectice questions, and ncert must read.

Well, it's a good decision that you have your goal clear at this point i.e. class 10th.
Well, cracking JEE Advanced requires a lot of dedicated work from day one.
For that, you need to clear JEE Mains first. And for that, you need to focus more on class 11th and 12th.
So now you know that it's not a one-day task but a long way to go through.
In order to crack JEE Advanced and secure a decent rank, you need to join some coaching institutes for help.
The rest is self-study and hard work.

No, till now, it has not been combined. This year also, the JEE was conducted in two phases only that is JEE Mains and JEE advance. The notifications of any changes will be notified on the official site of JEE Mains.

No, you can't do that now. Once the form is submitted and the examination is conducted nothing about the changing can be done, unless it is done during "form correction" procedure. The form correction process comes many days before the examination. JEE advance offers the last chance to correct the basics incorrect details. But still, the category can't be changed.

Well, this is against the rules. There is no provision of attaching the certificates and making any amendments after the examination has been conducted. You should have uploaded the certificates along with the form at the time of form filling and payment. You will be regarded as general candidate now.

I guess, the best would be from resonance and Allen. These have relevant questions and right pattern.

Well, you need to go for the standard books for JEE Advanced which includesu201d
-IIT mathematics by Das Gupta, TMH Publications
-Numerical chemistry by Prakash Bahadur, TMH Publications, Solomon and Vryles for organic. -IE Irodov, TMH Publication for physics. I hope it helps you. Prepare well and solve the past years papers from MTG publication.

They will tell you if you get any seat, then you have to select in which college. You can verify your documents.
