Hello Sameera,

You can visit various websites like Career360, Shiksha, Collegedunia, MBAUniverse and you would get a few previous year papers for ATMA as well as MAT.

ATMA - The pattern is more or less the same as every other management entrance exam. You will have reasoning, verbal and quant sections. So time management and accuracy should be your key as they have kept negative marking. Identify your scoring sections by taking plenty of mocks and focus on them more than the other sections as you will have a chance of losing out marks if you dedicate more time to the weaker sections.

MAT - If you are strong in GK, well and good. If not, there is no need to panic as you can score well by concentration on the other 4 sections. Concentrate on comprehension and vocabulary in Verbal; LCM/HCF, Probability, Mensuration and Geometry in Quant; Family Tree, analogies, direction, series, cause & effects, distribution, assertions in Critical reasoning; Charts, graph and data comparison in Data Sufficiency.

PS - MOCKS, MOCKS and more MOCKS. This is one golden rule that you cannot miss out under any cost for any management entrance exam. You need to leverage your strengths and let go of your weakness in these exams because smart work is very essential. For that, you need to practice a lot of mocks. So please be consistent on it.

For books, you can follow the Pearson books or the complete guide available in the market. To be honest, books do not matter a lot because the syllabus is more or less the same for all these exams. You just need to practice these questions, get hold of previous year papers and mocks and be consistent with them.

Hope this helps.
