how to crack the exams more efficiently??

first thing don't panic,it happens to most of the students who are in their final year of graduation bcoz the pressure starts to peak at this stage. make a complete list of works you have to do in the sense what you to study,are there any pending projects and all that,now make an organised schedule of what to study on what day what to do by the particular deadline,etc.and sincerely stick to the schedule,i mean dont compromise in the schedule unless it is inevitable. and have confidence that you could reach your targets as per the schedule. all the best

Don't set very big goals at a time. Do things part by part, like instead of making 1 chapter as your goal, try to complete just 1 topic at a time. Remember if we are given a lot of food in a single serving, we are reluctant to eat any. But if the same food is given in smaller proportions in a lot of servings, we feel like eating it even if the total quantity is the same as the last one.. Hope I've been of help. Take care, happy lotting !
