How to increase mock scores

So I've started my prep from April, my clat scores are around 50 and ailet scores are 70ish so idk how to increase them, how to do gk part and maths. Can someone guide me or share some tricks on how to tackle these questions and mocks? I attempt 100+ in ailet and around 90 in clat. I do good in english section and legal, lacks in gk and maths, logical is 50-50.
