Hi, I have 4+ yrs of experience. This will be my 1st and last attempt of CAT. I recently joined this program. So far I've been doing pre-readings(both beginner and advanced) and concept tests mostly, as I do not have time to attend the Live classes due to work timings. I am able to see the videos during my Bus journey and practice a little in the night and on weekends. Any suggestions would be appreciated.

Hi, I was told by my mentor to do 30 practice questions everyday after learning that day's concepts. For example yesterday I learnt LCM, HCF and divisibility. So I should only practice these topic questions right? Where can I find them? In the study room I can only find questions from the full Number System topic which I have not yet completed, like Remainder theorems I have not learnt and cannot answer those questions. So is there somewhere I can find only questions of HCF LCM, divisibility, etc?

HCF of (9000,X)=60 where x is a natursl number less thsn 9000 find the possible value of X ?
