It could have done better as a multichapter story. Still, I think you did a good job!

...wow. blew my mind. thanks so much for this.

Clap clap. Awesome. Touching, and awesome.

Wow. The dynamic here between Arnold and Ms. Frizzle was awesome, and the ending was beautifully poignant-this fic is going to stay with me for a while. I would have loved to actually see scenes of Arnold coming into his own as he gains confidence as a teacher, though. Write more? :D

OMG, this was amazing. I just...have no words for all the feels. ;_;

Wow; this was really intense and made me feel something. I'm not sure WHAT, exactly, but here I am complimenting you, so it may have been something good?

Awwwwww. :( Poor Ms. Frizzle and Arnold.
Loved the story. As someone that went through student teaching myself, very accurate indeed. :) Well done!

RIP Miss Frizzle :(

This was good, sad but good, I always wondered what happened to the kids when they left Ms. Frizzle's class.

Amazing story!

Kinda reminds me of 'Mr. Magorium's Wonder Emporium', the student becoming the teacher. So sad...

I really liked this story! Maybe you could do a sequel of when Arnold actually takes over the class. Great job:)

I had to say: the story was wonderful. It certainly does bring some depth to the basic premise and it's quite lucid, that depth. I for one wouldn't mind reading whatever filler you had planned for this. In fiction, much unlike video, there's much to relish in extended exposition. I hope you write more along these lines. Cheers!

Lovely... It's all poignant and sweet, and is a possible theory as to why Ms. Frizzle doesn't seem to age. :)

A/F is WIN! :D
