Hello Sumedh

Polish up your concepts with repeated numerical solving. Nothing helps better in polishing up the concepts than solving numerical. Hammer your mind regularly with more and more numerical problems. This will help increase your conceptual theory.

Establish your expertise on Aptitude and Engineering Maths as they are high scoring sections then pick up 4 topics from your stream that have the maximum weight age and get well versed with them.

Keep formulas on your fingertip. Concepts are no good if you don’t remember the formulas. The formulas should be so engraved in your head that even if someone woke you from a slumber you just start reciting the formulas.

Solve previous year question papers. This will help you to understand what kind of problems come in the exam and how to manage your time.

Try and give as many online mock tests as possible to get a feel of the test environment. Tests will help you analyze which areas you need to improve on. Whether it is the conceptual clarity you need to work on or is it silly mistakes that are costing you marks.

Hope it helps you.
