A professor offered to meet with me later this week to discuss some potential projects, and asked for my transcripts to see what courses I have taken and how well I am at them.
I have done decently in my mathematics courses, however, one semester last year was exceptionally bad for me and I ended up getting a C-, C+ and a D- (in discrete math, Introduction to C, and a biology course respectively). The only course that has some sort of relation to the research I'm interested in doing is the intro to C course.
I honestly don't know how to proceed with this. I don't want to keep making excuses for myself because I'm not doing incredibly well in my professor's class, but I know I can get better at the software being used (MATLAB), as I've used it before for maths classes and haven't had much trouble with it. I know he thinks I'm not the best programmer and I don't know how to deal with that idea and this situation.
How do professors deal with this? I don't want to waste his time, and more importantly, I don't want to become disinterested in the project and end up giving up halfway.
