The best paper according to us, to study along with MA would be PM. Only reason we would suggest PM because PM builds upon the contents of MA, think of it like the big brother of MA, though will say, PM is definitely one of the more trickier subjects of the skill level, so proceed with caution, but because of the similarity in concepts, and MA as a base, it is the most logical next step.

Another option you should consider would be to take LW, since it is mostly of the same pattern as MA, MCQ and on demand, you might be able to cover up quickly without wasting a lot of time and get one more paper out of your way, make sure to practice and give mocks!
