What's college life for engineers?

Which classes you take will depend on your major and college program but in general engineers take a lot of advanced math and physics. For math it'll be calculus AB,BC and beyond. If you choose chemical engineering you'll take chemistry, if you take biomedical engineering you'll take lots of bio classes, etc.

College in general will be more difficult than high school even if you're taking several AP classes in high school. For engineering classes the freshman and sophomore year will have several tough classes designed to "weed out" prospective students from the major. What's left will be the students who are really dedicated to majoring in engineering and willing to put in the work.

First decide what engineering field you want to go in, then look at specific school that you'll want to enroll in. If you're getting A's and B's in highschool and did well on the SATs and stay focused in college you should be able to succeed. Do not expect to go out partying every weekend though or do homework/projects the night before and also get excellent grades. College requires balancing your own work/play schedule since professors do not directly get involved with students as much as high school teachers do.

I'm enrolled at the University of Waterloo for systems design engineering, but I'm currently doing an internship at Zynga. I agree with what Eva and Shannon have said; take a look at any college / university's website, and they will likely show you what courses are available for your program. (Here's what courses I take for my program)[https://ugradcalendar.uwaterloo.ca/page/ENG-Systems-Design-Engineering]. College / university is typically more challenging than high school, but engineering is even more so. There is definitely time for having fun, but make sure that you always put school first. It isn't uncommon for a handful of people to fail a term. These people failed because they didn't put school first, whether their attention was focused more on partying, a relationship, or mental health issues (which is a more difficult problem than the first two I listed).

Having said all that, if you put school first and make sure you're prepared for your assignments and tests, you won't have any problems.

A Bachelor's degree will typically take 4 years. Engineering curriculums tend to be quite defined. If you have a school in mind, look at their website. Many schools have a list for each major of the courses required and when they are typically taken.
