I had to say it two times. Allow me to explain.

My name is Anzei, and I've just chosen game design as my college course, and my class will start on September. The thing is, I am completely new to game design. I don't know anything like C++ or other stuff, but I have heard that these are languages and there are more. So this is my first question.

1. What are the different languages, and what should I choose since I am completely new?

It's not like the thought of game design just popped out of my head when I was filling my college form, I've thought about it for a long time, and have been using this simple program called RPG Maker VX Ace, and have dabbled in the arts of making a game. I still do not know how scripts work, so I use scripts that are free in the web. Also, I do understand that game designing involves Math, a subject I am not that good at, but I am willing to learn, just like when I was studying on how stats and formulas work on RPG Maker. I'd also would like some tips on how I should continue with this choice of mine, for the people who have walked this road before me.

On a side note: Sorry if my English is bad, it's not my first language, but I am studying it.

There's a FAQ for begginers here that answers your question and probably the next 2 or 3 you'll have: http://www.gamedev.net/page/reference/faq.php/_/for-beginners-r1

Whatever course you are attending will introduce you to whatever language that course uses. Some courses still rely on C++, which is a little heavy for an intro game design course. Others will use Java, or perhaps C#, or Python.

Point is, learning C++ won't be of any immediate value if the course uses Java, or vice versa. Get the syllabus for the course you're signed up for. That should point you in the right direction.

Greetings, Anzei. Your English seems just fine to me -- better then some of my native English speaking students! I'm not kidding (which is sad).

Anyway, read those links. I'd like you to clarify what your goal is (if possible this early in your studies). Are you thinking of focusing on programming? Design/mechanisms? Art/modeling? A little of everything?

Best of luck to you.
