Natansha,

From my first attempt on 1-Mar-2025, I would recommend you should be equipped with basic Geometry - areas and perimeters or 2D shapes atleast (Square, Rectangle, Cirlce). Below is a DS question that I faced about mid-DI section (Yeah, I recall the question vividly, the 2 statements roughly).

"A small coin of radius r, rolls on a surface for time t, covers a distance d and makes n rotations in its path. A bigger coin of radius R, rolls for time T, covers a distance D and makes N rotations. Both coins roll at the same constant speed. What is value of n/N ?"

The two statements were something like - first statement gave a relation of r and R, second one provided a relation in t and T. Don't exactly recall the 2 statements, but the question stem was exactly as above.
Did you come across such ques in Official guides or mocks? I will definitely go through the basic formulaes, but still need to practise such ques coz it will through me off in the middle of the exam
