Dear aspirant,

No, that won't be enough for jee advanced only by practicing previous year questions. You have to follow and pratice from some textbooks as well.

For Maths- You have to follow the Arihant series particularly the algebra and coordinate geometry part. There are a lot of solved problems. Atleast go through that.

For chemistry- For inorganic just follow JD LEE ,the concepts in that book would be more than enough for jee advanced. It would rather help you to solve inorganic questions with some tricks. For physical  P.Bahadur would be enough. Just practice from there. And for organic practice M.S chauhan.

For Physics- If you have joined some coaching like fiit-jee and allen then their course material is very appropriate and you can practice from their assignments. Otherwise follow dc pandey series.
