For MSR, start by quickly scanning all the tabs to get a sense of where the relevant information is, so you’re not wasting time on details that don’t matter. Time management is critical, so practice answering questions in timed sets, and if something looks too complex, flag it and move on to easier ones, then come back to it later. For DS questions, always simplify the problem by breaking it down and asking yourself if you truly have enough information to answer. More mock exams under timed conditions will help you improve both speed and accuracy. Lastly, just practice more. Nothing beats practice, absolutely nothing. When are you planning to sit for the exam?
