My first semester I was a pharmacy major and finished my first semester with a 2.5 GPA I had a C in bio and a C in chem my advisor told me not to bother switching into CMD because I would never make it in, but I did not listen and I worked really hard. I brought my GPA upto a 3.4 by the time I was applying. It was not perfect, but it got me into 3 graduate schools and waitlisted at another one. I also decided to retake bio and chem because a lot of schools require at least a B In these courses. All the schools that interviewed me were really impressed that I was taking them again and I had already gotten my first exams back and had done really well so I was able to use these to show how I have grown as a student because grad school is a lot more demanding. I also did A LOT of internships and even had a SLP that had known me well write me a letter. So if is something you really care about DON'T GIVE UP just work that much harder to show yourself and them how much you have grown since that first bad GPA
