all the best!

For competitive entrance examinations, nothing can be guaranteed whether a particular knowledge about a topic is enough or not because the questions can be asked up-to any depth. At times, 2-3 chapters are also mixed to make a new question which gets very tricky. Yes but R D Sharma iss a ddecent book. So you can target on finishing that book at first and then if you have time, then you can go for others books too. A books by Vikas Gupta and Pankaj Joshi is also well known for JEE ADVANCED.
