Wow… I got a 1 and I’m going to be a junior this year. I definitely need to retake it for when I apply, so I’d be interest in anyone’s suggestions for studying. I already have a lot of CS knowledge. I even have a nice looking github profile. I just didn’t really study well for Java and the CS test… So disappointed and need help.
My advice for you is to pick up Python and start looking at other Bio/Neuro programming projects. Look at the code. Then try and come up with your own idea or look for ideas online. Python is really easy and a great language. The best way to learn at this point is to DO! Use online resources. If you get stuck and you’ve googled a bunch already, then ask for help on a forum. For projects, do what you want. I’m not a big fan of iPhone apps despite being a Mac and iPhone user. Web dev is a little over populated.
