The best way to learn something is to ask questions about it to yourself: 'why?','how?','what if?' and try to find the solutions, also by yourself. Make mistakes, as many as you can, at the very beginning of learning something and as soon as you get to know it was a mistake, correct yourself. An expert in a field is none but the one who knows every mistake anyone can possibly commit in that field. Learn to make mistakes the first few times so that you can shine when it matters most. You will not regret if you give a considerable amount of time in figuring out what you understand and what you do not. And if you have a passion, go for it, and stick to it. If you really want to be something, you can be. Believe in yourself.
My favorite quote from 'Batman Begins' is the one by Alfred Pennyworth: "Why do we fall, sir? So that we can learn to pick ourselves up." So when you feel down, when you cannot reach your expectation, motivate yourself for the next goal. If you try your best, you will succeed, sooner or later. Hard work pays off.
Never give up on your dreams!!!
CLOSING WORDS:
Results will be published very soon. Sometimes result rewards effort you put into achieving it, sometimes it does not. If you get a good grade, congratulations to you. But if you do not, then be advised to not lose hope and, at the same time, brush up your basics in the term break you will have and try to make up whatever you could not learn during this semester. Because, this was a core course and weakness in these topics will surely give you a hard time in future. Try hard, and well, I can assure you, success will come to you.
