See, according to some vmc teachers, vmc material is enough for jee advanced. It is up to the student to solve any other material.
It is totally up to you, if you feel that you need more practise then do solve other material. I think vmc material is enough for jee advanced.
I would suggest you not to solve jee main pattern questions of vmc supplementary booklet of some chapter because it is irrevelant.
Second, always do question in a time limit. Pick up some questions and do them in a given time interval. It will increase your speed.
Do not just run for other books. First complete vmc material and then solve other books if you have time. Never leave any test in these 2 years even if you are not prepared.
