There is still 5 months time (considering the exam doesn't get postponed and happens in the usual month of May) and in these 5 months of time, you can easily revise all 97 chapters and practice a few mock tests + previous year questions.

I would suggest you to prepare as if you are preparing for NEET UG 2022. This will be highly beneficial s ince chapters and syllabus of NEET UG and ICAR are exactly the same. Plus it is seen that, a candidate who performs well in NEET UG also performs good in the ICAR Exam.
