Hello Aspirant,

you should start from its basic by knowing its syllabus & structure of the exam then you should complete its syllabus. Revision is also necessary time to time. You can do so by accessing internet or can use books as IPU CET books are available in the market that give u a thorough idea of the exam paper. You may get previous year questions paper from IPU website or the book you are going to purchase will have some question papers attached with it.
