Hello , I joined cracku batch 6 in april and been following it since. would the given mocks be enough or do i have to purchase a test series.

It is always better to have test series of atleast 2 institutes. cracku mocks are good but not a lot of people give cracku mocks .so,it will be better if you have a mock series where 10 - 12 k people takes the test .so that you get an idea about your position in between that much serious participants. i also enrolled myself in cracku as well as time test series.
hope it helps.
