New beginnings..

Hello, today I want to express how I feel about a situation that I'll be going through the next four months. I've been focusing on expressing my emotions and feelings naturally in English, it is something I really want to accomplish indeed. (Indeed at the end like that just sounds strange, in fact it's quite an out-dated word) 

Next week I'll be starting college and I hope to do well with my studies. As I'll take my Calculus class with a demanding teacher, I'm trying to be confident and not to be worried about it even though a lot of people who were once his students have told me that his exams are really difficult and a very few people approve of his teaching/of the level of difficulty. Fortunately I'm very commited and disciplined, I don't mind if I have to spend the whole day solving equations/problems exercises, I'm willing to give it my best for it. I know our mindset can be decisive enough to accomplish anything we desire, therefore I'm preparing myself for success.  I know I can do it, also I need to keep it in mind but I have to keep that in mind if I want to succeed, I'll write it on my forehead if neccesary (Not literally). Regarding my English studies, I have to take a placement test and then I'll decide whether I want to take the class this semester or the next one. I hope to learn a lot this semester, learning is more important than approval but if we can have them both, isn't that a good deal? 

Thanks in advance for your comments and corrections, they mean a lot to my self-teaching process.

Best regards, Ana.

Keep on rocking your studies! Most of the correction I made were just to sound more like a native.
