Currently a double major Engineering major. Mechanical and Nuclear. I started off as Mechanical and added the nuclear option last semester. I did this not because I thought Mechanical was easy, but I felt like I had the potential to do so much better. A lot of times, getting that extra degree doesn't compound your workload each semester. It just increases the time your in school (4 years vs 4.5 years)
I highly suggest looking into a double major. Mechanical and Nuclear are the most common. I know Bio and Mech are also offered as well. A lot of times, the extra degree requires ~20 more credits or another semester, depending on how you arrange your academic plan. To me, the Nuclear degree is very worth it. I plan to use my Mech E degree (I want to be in the automotive industry) and use the Nuc E degree as my "backup", because you are pretty much 99% guarenteed a job outta school with a Nuclear degree, especially now.
Some advice I can give
1)Time management. Go hard with your studies during the week. Study during the day during the weekends and you'll be gravy. I still am able to go out and drink/party Thursday, Friday, and Saturdays every week. Except when I have an exam on a Monday the next week, then I usually stay in.
2)Pay attention in class. Turn off the phone or leave it at home. I'm still trying to figure this one out. I can't sit in front of a dude and listen to him talk for an hour. I do a bulk of my learning on my own and I KNOW that this is going to bite me in the *** sooner rather than later.
3)Sleep. Everything revolves around sleep. If you don't get enough sleep the night before, you'll be groggy the day after. You won't be able to focus in calss which requires more time outside of class. You'll end up taking a nap or drinking coffee and then taking a nap when you crash, further wasting more time. Get a solid 7 or 8 hours a night, and you'll be straight. College students know the importance of sleep but they don't understand that it is ESSENTIAL to success
4)And the most important piece of advice I can give you is push yourself to your limits both mentally and physically. If it seems that you can do more, pick up another major or even a minor. Fulfill your potential. You're paying a ton of money so you might as well get as much possible out of it.
Also, have fun, You will not survive if you do not allocate a couple hours every week to relax and have fun. You will get burned out, you will lose motivation and your grades WILL suffer. I can guarentee that. If anybody has any questions, feel free to PM me. I'm still in school as well but I can safely say I've figured out a good "technique" to it all
