What do i have to do in last ten days before mains? I have almost finished all the concepts and it is only practise that is left ,will previous years parers suffice or do i need to practise from somewhere else?

hi vaishnavi, you should solve previous year papers now and after each paper you gotta check out the solution for each questions, this will help you find your loop holes and you will get an idea to what you will be scoring... also keep on revising formulae, yeah you have finished studying, but this will help you recall things faster and there will be lesser chance of errors... hope this helps. cheers :)
