At his size/age, there's no way to say how big he'll get. Frag was about that size at that age - he grew QUICK. Then stopped, right around 75/80lbs. His dad was 120 fwiw.
Patton is growing slowly and is still small, but I fully expect him to reach standard.
That said, there should be no harm - there are much larger dogs than GSDs that run agility just fine.
I would however, stop jumping him and doing contact work NOW or you WILL have joint problems. I would not jump a GSD even 4 inches until at least 8 months - and I would stay there until a year. Teach the standards, wraps, crosses on the flat, you can work on a 2o2o if you want with stairs or a plank. Work on engagement and DRIVE. Targeting, sends, and lots of tunnels/chutes. No weaves until at least a year old.
Patton is almost 6 months old - he can send to a tunnel pretty well, wrap the jump standards, cross with me, and keep up. He's been on a wobble board and walked across dog walk planks on the ground and gotten to be around all of the equipment.
But some of it is just not safe for growing puppies because of the impact it places on their little (ok, huge..) bodies.
eta - I'm not sure where you're taking classes, but if they are recommended this for an 18 week old GSD, I would find a new place. You aren't that far from me - I can recommend a trainer in the Grand Rapids area that I drive an hour for class with if you'd like, and I also know a trainer in the Okemos area that may be offering agility training soon...
