Question about dot physical and CA dmv

I got the fmcsa spe certificate today. I wasn't sure if I was going to get it or not since I never heard from fmcsa. It's a temporary one so after I get my license I have to fax a copy of the front and back of my license then I will get the actual 2 year certificate. Hopefully in two years I will not need it. My doctors told me my nerves should be healed by then or alot better where I could move better. I drove today for the first time. I practiced starting off in the school's skill yard, and backing and driving in circles. The instructor was suprised how well I did and let me go out on the road. I guess he was worried about my ability. I did okay just have to get the hang of shifting quicker and double clutching. My downshifting needs works also. I guess not to bad for the first day driving. The truck is a '95 kenworth t600. The brakes on that thing are super sensitive. I thought every one was going to go through the window. When I got back to the school they let me back in the truck and trailer into the yard. The school is at the end of a culdesac so you have to whip it around and then back it in around a gate. I want to get in the T2000 that the school has. I was told the brakes were less sensitive. Thank You all for the help so far. I really apreciate it.
