Dedicate one focused hour in the morning to QA formulas or an RC passage, one hour in the evening to DILR sets, and reserve weekends for full-length mocks and thorough review.

It is not too late, provided you adjust your scope. Focus directly on core topics, start taking sectional tests immediately, and spend time learning through mock test analysis.

Focus on formula sheets, mental math tables, grammar pointers, and your accumulated test error log. Avoid attempting full-length tests during the final three days before the exam.

Enrolling in a classroom programme is rarely practical with two months left. However, a dedicated mock test series or a targeted crash course for specific weak subjects can provide structured practice material.

A beginner can build a respectable attempt by focusing strictly on high-yield areas such as Arithmetic, Algebra, core DI arrangements, and Reading Comprehension, rather than attempting the entire syllabus.

Taking 12 to 18 full-length mocks across the 60-day window is generally sufficient. Candidates must scatter these mocks into phases and dedicate at least three to four hours to analysing each test.

Yes, 60 days is adequate if you have a basic understanding of mathematics and reading skills. It provides sufficient time to revise concepts, complete timed sectional practice, and take 12 to 15 full mocks.
