Regardless of whether your move forward in this major or change to another one, you still need to refine your study skills to be successful. Realize that you must study long and hard for any worthwhile career...period. What you are doing now just isn't enough. This is something I had to learn when I found myself struggling in school at one point. But I'm the kind of person that if I make a lousy grade I immediately have to stop and reevaluate what I am doing. As they say, "The definition of insanity is doing the same thing over and over and expecting a different result". If you are making Ds then there is something you must change in the way you are approaching your studies. Luckily you're only a sophomore now so technically you do have enough time to pull up your GPA but you will only be able to do so by changing what you are doing. I understand not wanting to change your major (I changed mine 3 times before finding SLP). What you need to do is find all the resources you can to teach you how to effectively study the material. Amazon, youtube, pinterest, tutors, professors. There are tons of resources available. There is literally a book called "How to Study"! Good luck
