hi,

see you need to study the syllabus accordingly and focus on the topics which has most questions coming from. jam is conducted by iit,  so question level is harder than any other university . you need to do more practice and solve previous years questions. follow any good books for model questions.

Hello Bhuwnesh,

The only solution to this problem is that practise previous year question papers. Just change the books from which you are studying or probably your strategy is wrong. Try clearing your concepts first, and then practise relevant quesiton from previous year question papers or genuine books. Try attempting questions concept wise, rather than attempting any random question.

Hope this Helps
