That's really useful, thank you

One thing though, is 'over there' America or England?
But cheers alot, that's saved me hours of staring at a website in a daze.
The way I understand, tuition in the US for college is much higher than in the UK. Especially Harvard, that's one of the best schools in the nation lol.
To answer your questions in the OP, the typical college age for a person in the US is starting at 18 years old, but there are those who start in their 20s or even 30s. The track for most college students these days is you graduate from high school at around age 18 (I believe you call it primary school, but basically it's the part of our education that is compulsory) then you go to college right away. Usually you graduate from high school in the spring, and then in the fall begin your first semester of college. But there are plenty of people who put it off for a few years, or even come back in their 40s or 50s. As long as you're under about the age of 60 you aren't going to be too out of place going to college in the US, lol.
Your "major" is essentially what your degree is aiming for. My major is computer animation, and the degree I will receive will be a bachelor of fine arts in computer animation. I don't have a minor, because computer animation has enough classes involved in it to fill the entire program on its own. Don't quote me on this, but I
think the purpose for a minor is supposed to make your degree a bit more specialized. For example, you can major in communications, but minor in Spanish or some other foreign language if you want to be a translator. So choosing your major is essentially choosing what type of degree you will receive and what your area of emphasis.
The "rankings" (freshman, sophomore, etc) refer to what year of school you're in. Most bachelors degrees take 4 years to get, so your first year you're a freshman, second year you're a sophomore, third year you're a junior, and your fourth year you're a senior. Then there are "super" seniors, which is what you call someone if they're in their fifth year of a four year program (that is a more common than you would think--in the US the average college student changes their major at least 4 or 5 times). Most people I know will be finishing their programs late, because of either changing their majors or just poor planning on their part.
Once you start Master's degree programs the idea of a freshman and whatnot sort of fades away. Master's degrees can take anywhere from 4 to 8 years to get, depending on the program. Associates and bachelor's degrees are called "undergraduate degrees," and Master's degrees and up (up through Doctorals and PhDs) are called "graduate" degrees. So when I get my BFA, I will be an undergrad. I could go to graduate school and get a Master's, but at this point I'm not going to invest in that.
I hope that helps you get your head around the terminology, lol. If you have any more questions, feel free to ask.
