Whether you should retake the class to get a better grade depends on the requirements for the dental hygiene program(s) you are applying to and how competitive it/they is/are to get in to. If program entry is highly competitive and you have time, it might be a good idea to retake. Otherwise, you could apply, and if you don’t get in, you would have a year to retake. Only you know the best course of action for yourself. 🙂
From what I recall, it was only required that I pass the humanities with a 2.5 GPA or higher. In fact, I didn’t pass one of my math classes at that level- I was .11 points off, I emailed my instructor and asked if she would consider giving me the 2.5 since she knew I had tried really hard in the class and participated and was very active in my education and honestly just had a difficult time understanding the material(it was an online math class-yikes!). She agreed and gave me the 2.5. hat mattered for my program were the biology and chemistry courses- which I got 4.0s in. I wouldn’t stress the class as long as you got the minimum required GPA. I also later found out students with much less impressive GPAs were accepted into the program.
