Thanks for the advice! Based on what you said, I think I'm going to have a tough time getting accepted into a graduate program. My first three years at college were spent bouncing between majors, so I don't have strong relationships with any of my CS professors. The only time I would say I excelled was my senior year where I completed 8 cs classes with good marks, but that doesn't seem nearly as impressive as completing undergraduate research/an internship. Do you think open source work/self studying in the field I choose will have a large impact on my potential acceptance? I regret not focusing in on CS and math earlier.
