CAT

This is a long one to answer, but I will give it a try. MAT and CAT are really different to their core. The only similarity between these two is that on cracking any one of these, you will end up with an MBA or PGDM. Let me summarize the differences in the following points. Paper Pattern - The MAT paper has 200 questions divided in 5 sections with 40 questions each, whereas the CAT paper has 100 questions divided in 3 sections of 34,32 and 34 questions. MAT has a section called India and Global Environment which is based on GK. However CAT doesn't have a GK section unlike some other management exams. MAT has a negative marking of - 0.25 marks and CAT as a negative marking of - 0.33 marks per question. Test Taking Time - In CAT one gets an hour for each section and the whole exam is of 3 hours. In MAT one gets 150 minutes (2 hours 30 minds) for answering the 200 questions. Paper toughness - The MAT paper is really easy compared to CAT. The questions are easier and also it's easier to score high percentiles as the test taking lot is not as serious (By serious I mean some of them CAT takers give 200 or so mocks, which is unbelievable) as the ones taking CAT. Test Frequency MAT happens 4 times every year while CAT only happens once a year. So one has a high probability of cracking MAT than CAT going just by this.

Hi Saumya!
There are different entrance exams for MBA such as CAT CET, CMAT, GMAT, NMAT, SNAP, XAT, MAT and ATMA. Out of the above mentioned exams, some are some exams are college specific (NMAT, SNAP XAT I. e. you need to appear for those exams to get into the college. While others would widen your scope and choice to choose colleges. Also, consider that there are colleges who do not accept all the exam score and restricted to certain exams only. But I would suggest you to appear as many exams as you can. I would suggest you to give an attempt for CAT CMAT CET, NMAT (Must Attempt according to me). You can appear for CAT this year and other exams to. In case of re - attempting exams the following year you can also search out for internships to gain some work experience in the field of your choice. But do consider giving other exams too. All the Best Mate!
