One of the most effective study tip I have ever received is to understand the topic by putting efforts not go for rattafication because it will have great effect in future as well. If we understand a topic fully-fledged in depth then it will be useful in exam and future needs also. Using this tip you will also enjoy your study session and you time will not gonna vain. Examiner can also be impressed with you by seeing the in-depth knowledge you have about a topic and he/she knows that how much you have understood a topic.
