Okay, girl. Here's the thing, you need a reset. I am assuming that you are a true sophomore and have just begun to really dig into your classes. I was a high school teacher and did very well earning my degree the first time around. I decided to become and slp and it is a lot harder than I thought it would be. Study in a different way, visit your profs during their office hours and get all the help you can get. Just because you don't get it the first time doesn't mean you can't get it at all. Pick yourself up, dust yourself off and walk back into the game. If nothing else, it will be a great perk on your SOP in the end. There are a ton of things that can make you a viable candidate. The thing is if you love it, it's for you. You can find a way. If, on the other hand, if it's a combination of not enjoying what you're studying with not doing well in class - that's different. Follow your heart.
