Welcome to Adda
Firstly, go through the previous year's CAT papers, as it will give you a holistic view of the exam structure, the topics tested, the exam difficulty etc. (we provide all CAT previous papers with detailed Video solutions. You can download PDFs here: https://cracku.in/cat-previous-papers).
The next step would be to take a free CAT mock and analyse it well. Make a note of your strengths and weaknesses. Draft a study plan based on your analysis, and try to stick to it rigorously. (You can make your own study plan or simply follow this study plan made by experts: https://cracku.in/cat-crash-course#schedule)
Make sure you balance all the 3 sections, as there are sectional cutoffs for most top b-schools accepting CAT.
Once you make the schedule your prep begins:
1) Learn the basics well, and practice questions regularly.
2) Take timed tests (topic tests, sectional tests, full-length CAT mock tests).
