Hello everybody. I am interested in learning Physics but I have a bit of a dilemma. I am not sure which Physics course I should use to start off. It seems to me that Physics NGSS is more concise, but probably doesn't have all of the course material yet. Whereas Physics does seem to be completed. My question is should I start with Physics, and then when I am done, move on to NGSS, or should I just do one or the other by itself?
