Overwhelmed in PTA school

Hey all, I am a SPTA and I would just like to know how you guys felt when you guys started PT or PTA school.

I am currently in my first year 2nd semester of PTA school. I am amazed at all my classmates how well they are grasping concepts such as; stretching, AAROM, and resisted training. They are able to come up with great Therapeutic Exercise program on the fly. I do feel overwhelmed by their thought process and at times get discouraged because I am slowed at coming up with programs. I understand how each joints of the body moves and some muscles that are involved with those particular joints. What amazes me is how deep of a thought process my classmates have. Is it okay for me to feel like thiis?
