Is giving DAMS GT worthful or should I attempt Marrow GTs only??

Because I attempted one dams GT and total candidates were only around 2k … while on marrow there are 40k.

Or can anyone suggest any other platforms for GTs?

Dams GT the level is too high plus it’s tough ,so don’t think they do simulate the real exam question levels.Whereas marrow questions are close by to NEET and yes you have more people giving it so you get an idea
