I'll hit you with the bad part of if upfront....Whoever said "college was the best years of their life" didn't major in chemical engineering. Do a Google search on "most difficult degrees" or "most difficult undergraduate majors" or something to that effect and you'll likely see chemical engineering pop up a lot, alongside physics, other engineering disciplines, etc. I would plan on devoting a lot of time towards studying, especially if you go to a top engineering school. I studied around 60 hours a week when I went to Georgia Tech, and still failed the majority of my tests (without the curve). Good universities tend to make it a point to make the tests impossible, so rather than trying to get a 90 average to make an A, you compete with your classmates and it's understood the bottom 20% of the class will drop or make a D or F. The rest of the grades are distributed based on a bell curve where a certain percentage of the class, gets an A, B, etc.
Having said that, although chemical engineering is an extremely rigorous undergraduate curriculum, it's also very rewarding. Check out what typical chemical engineering salaries are at the below link as compared to other occupations.
http://www.bls.gov/oes/current/oes_nat.htm#15-0000After you graduate with your degree, your potential employer will know that you are a bright individual just because of the degree you graduated with. There will be many opportunities because of this, and you will be rewarded for your hard work. Even if you decide not to get a job in chemical engineering upon graduating, there are still so many opportunities available to you, e.g., medical school, law school, and just other jobs that are completely unrelated because an employer knows if you can graduate with a chemical engineering degree, you have the brains to figure out basically any line of work.
Just as a few final points:
1. Make sure you like chemistry and math prior to majoring in chemical engineering. You'll be taking 4 or 5 maths and that many or more chemistry classes. Then the chemical engineering courses will more or less be a combination of the two.
2. Make sure you do at least one or more internships. Not doing any internships was the biggest regret I had. If you don't do that, your relevant job experience will be blank on your resume' when you're applying for jobs.
3. Make sure you keep your GPA as high as possible. After graduating, your GPA is that single number that everyone has that potential employers can weed you out on for it being low or give you extra consideration for it being high. Many employers will just use a cutoff of 3.0 or something similar to narrow down the applicant pool for entry level hires. As you progress through your career, the GPA becomes less relevant when applying for other jobs, but that's something always sticks with you.
