Your freedom is only in the field of action, and not in the field of bringing about the fruits of action. Never take yourself as the cause of bringing about a karma-phala (situation).You have to do your karma and leave god to do his due, if you've done the required hardwork, given your heart and soul to the preparation, you will win the battle.. no matter what happens. What targets you should set for yourself should not be the number of marks scored in exam but the number of chapters/modules completed with excellence.
This is also substantiated by ramayana..
"Jaki Rakhi Bhawna Jaise, Prabhu murath tin dekhi vaisi"The message is clear.. You have to go with the positive attitude that will provide you the required mental strength. On the contrary, the negative attitude or pessimism or the unnecessary fear of failure will deter you to prove your talent and exhibit what you truly possess. It then leads to nervousness and frustration. So following the message conveyed by the great epics.. Go with positive attitude & optimism.. Do your karma religiously.
God is there to protect us, "Have faith in His existence".
