I'm assuming that means you passed a medical exam, did you opt for a 1st class or a 3rd class exam? It's the first step on a long road. If all you want to do is get your Private cert, it's a big step in that direction. If you have higher aspirations it's the very first tiny step and, although I'm unsure of your age I assume you're a younger person, you should make sure to get a 1st class medical right off the bat, that's what I did. It would suck to think you're fine and then get the rug pulled out from under you after you've spent a LOT OF MONEY and your aspirations are tossed. If all you want to do as a pilot is fart around in a 172 you're on the right track. My only other suggestion would be to have the money up front when you start. When I was a very young man working GA line service at Burbank I had lots of connections and friends and I had a couple false starts trying to get my PPL, the training was a lot of fun, but it was disjointed and it always seemed as if I never made any real progress because I wasn't able to fly consistently at a point when that was what I needed most. Eventually my fortunes changed and having a curriculum that not only I was bound to (because I paid for it) but so was the school resulted in me finishing very quickly and had a great experience. I'm not trying rain on your parade, I'm just telling how it worked for me.
