I am not able to increase the mock scores, what to do?

Identify your weak areas by properly analyzing your mock. Work on them for 3-4 days then give another mock. See what has improved and what has not. Then again repeat the process. For quants, revision is important. For VARC, give sectionals of previous year questions. It is available on Cracku. LRDI also just practice and practice, especially attempt the previous year questions.

I fear doing any of the mocks and sectionals...till now I haven't even gave a single mock, as my syllabus isn't complete also as a non engineer I've some serious issues with quant and basics can anybody tell me what should I do?

CAT in less than 2 months. Forget syllabus. Carry what you have learned. Make it better rather than focusing on new topics. And start giving mocks. There are so many free mocks available. Go for it. Test yourself.

hey even some non engineers had able to secure good percentile around two months...if u looking for assurity whether u would be getting ...please dont go searching for answers instead put ur full effort for two months like a challenge ...study from basics to advanced whichever topic you feel comfortable and give ur best shot at it...i hope this would give u some motivation ....Yes ur mocks are also important because from mocks u not only learn things but also u will get an idea of strategizing things...so take atleast 10 mocks that gives u glimpse of understanding about how to tackle ur weakness...dont put too much pressure on marks...instead focus to learn a lot...All the best for ur 60 days challenge
