Hello guys I wanted some honest and genuine opinion from all of you

Hello guys I wanted some honest and genuine opinion from all of you. As I got a research job I would be starting it from September 25 and I have just started preparing for step 2CK so basically from today till 25th I have exactly 2 months in which I am totally free and have no work to do so can you please guide me how should I utilise these two months to prepare for my step 2CK because once the research starts I would be very busy from 5 to 5 and would have very less time to study so I want to maximise my time right now and utilise it properly so can you tell me how many blocks of uworld should I do for these two months as I am totally free And any other strategies that will help me for my step in these two months. Because I don’t want to keep delaying my step 2 once my research starts and want to be done as soon as possible.
