Is it sufficient..?
I have found eis notes in free resource section as well as in the course ( I purchased eis subject ) . The q&a in free resource section are shot as compared to those provided along with purchased subject , Will it be appropriate for exams if I study free recourse material..?
Yes. The ones in Q&A format are given for exam oriented preparation.
So what can I prefer , the q&a provided to me along with the lectures or free resource material..?
