Oh cool, my brother's going into computer engineering as well. My dad's actually an aerospace engineer, I look up to him a lot and I'm identical to him in method of thinking, personality, pretty much everything. A 3.5 (out of 4.0) in scale is in between a B+ and A-, a little closer toward A-. My last grade was actually put in yesterday so it brought me down to a 3.4 though. Sounds like you did well on your exams so far. Really anything B average and above is excellent in the engineering field
