My 6th flight

Well I got to fly a Cessna C150 for the 6th time this weekend, I did the taxiing, takeoff, landing, short field landing on grass, and a short field takeoff on grass.
And this brings me to my question, this summer I'm starting my PPL training on I was wondering what are all the medical exams and such that have to be done before the first flight and if I'm 16 now can I get my PPL before I turn 17 or must you be 17 to finish the training?
I took some pictures but I lost one of my camera battery's in-flight and it rolled to the back of the cockpit some there are only 2 pictures
Holding for takeoff
En route to KLKR

Another thing one of my local airports is having an airshow on May 17-18 and if your in the area it should be worth attending heres the website for more information http://www.flylkr.com/ 8-)
