I am in a bit of a pickle and I need some advice. I'm new to this website so if this goes in the wrong thread, I apologize in advance.
A little about me, I'm 23 years old and decided to go back to school this spring 2013. I have taken some college classes before, after I graduated from HS but I wasn't sure at the time what I wanted to do and felt as if I was wasting my time. Therefore, I didn't put forth a lot of effort and my grades were poor. So, I quit school and started working construction for a few years. I then realized that I wanted to go to nursing school because I want a more rewarding career, I enjoy helping people, and I want to make a difference in the lives of others. I hope to one day obtain my Masters or Doctorates and become a CRNA.
I am taking Intro Biology this semester and my professor is extremely knowledgable on the subject. But, he is not a very good teacher. He is very sarcastic and when asked a question he makes students (I typically don't speak on behalf of others but the class went from about 60 people down to 7, so the few of us remaining have become pretty close and talk often) feel belittled and for lack of a better word, dumb. When going to office hours to review exams he only allows his students 15 minutes to look over the exam to see what they have done wrong, then we have to return the exams to him. Needless to say, I am struggling in his class, and with the final exam in 4 days I will have to score better than any of the previous exams to barely pass with a C. My question is, if I pass this class with a C or C-, would it be wise of me to retake Intro Biology (with a different professor) in the summer or next fall, due to the amount of importance that is placed on science courses?
Any advice, study tips, or constructive criticism on this topic and the path to becoming a CRNA is greatly appreciated.
