Please suggest the best online test series to take(both subject wise and grand test) among the following options
a) dams
b) bhatia
C) prep ladder
D) marrow.

I am not talking of going and writing offline test. Or test and discussion series. I just want honest review of best among these to take up online tests.I am looking forward to joining any one for self evaluation. So,
Please don’t promote or bring down any institution. Just honestly help out a fellow junior with your suggestion. Thank you.

Both dams Nd marrow. I did the grand tests from DAMS but d fr topic wise, subject wise tests —marrow is d better one.

One is not enough
Choose any two
Marrow +Dams

make sure ur giving atleast 2 (or even 3) GT per month apart from SWT

whats different or special in marrow test series compared to dams test series

Galati se bhi prepladder mat lena. Sabse worst hai. Most answers wrong even the explanations are wrong. No or very few image based questions . Since they also provide dental , neet ss , civil services test series , so neet pg gets divided attention.
