Question for newbie with x plane 12 flight school purchased from x plane

I used X-plane 11 on an iMac, was old but worked ok. Wife got me new gaming pc to put X-plane 12 on! It's working well! I bought the flight school from xplane.org. I got it registered, and it shows up in x-plane 12.

My dumbass question, How do i change the plane? I don't want to go through training with a Cirrus SR22.
