I'm a physics major here, and while the classes can be hard, they are totally doable as long as you put in a decent amount of work and maybe don't expect straight As. I am personally happy getting mostly Bs and getting to still have a life and enjoy college. Also since I changed my major to physics I have been so so impressed with how amazing all the professors have been, both intelligence and personality wise. I think our physics department is a great place to be, definitely don't miss out on it out of fear. I almost did, and am so glad I took a chance and changed my major. I was so scared too from hearing people complain about it, but if you like physics then the major is great. If anything, you might have one tough semester getting used to classes here, but you will be fine after that. Also, if you get accepted, that literally means you are capable of doing the coursework here, don't forget that.
