Hi aspirant,

For the best CMAT preparation, begin 5-8 months before the exam date, allowing enough time to cover the syllabus, practice different question types, and take mock exams. Make sure to spend enough time each day preparing for the exam and focusing on your shortcomings. Once you have completed the syllabus, take mock assessments to assess your preparation level and find areas for improvement. Also, recap key concepts and formulas.

All the best!
