I know that there are quite a few relatively similar posts, but for my own assurance, I would like some input/guidance regarding the possibility of pursuing a physics or engineering degree. I'm 29, so the prospect of returning to school is rather daunting. To be clear,my high school academic record is absolutely awful (D average), and I regrettably pursued a GED rather than a diploma. While I was able to comprehend and complete the work, for reasons that I will not elaborate upon, I chose not to. Over the course of a few years, I picked up books on mathematics and found it rather enjoyable. On occasion, I hire students from the local university to tutor math. The more I read about math and physics, the more I desire to learn. I can't imagine anything that would be as desirable as a physics or engineering degree, regardless of future earning potential, job prospects, etc. etc. I want to do this for the knowledge, not the money or the "look what I did" factor (although I do have the deepest respect for physics, math, and engineering majors). To make an already long story short, I'm actually terrified of what to expect when I apply to colleges. I understand that I'll have to take the SAT/ACT and spend a couple of years doing well at a community college to make up for my past academic follies. However, I'm afraid that all of this won't be enough. I know that it's going to take a sizeable amount of work, but I'm afraid that my applications won't be well received by universities because someone who's almost 30 with a GED wants to study physics. Should I bother, or do I have a legitimate shot at this?
