"Marks for Effort" - Adorable. Cozy Glow is an immensely charming new character, and I loved seeing people outside the main student characters in the school. Most of all I loved how this was able to keep the CMC in a mostly admirable role while still having them learn something. That they tried to get into the school, and were partially tutoring Cozy Glow in order to experience her homework vicariously, sets them up to learn something just like she did - they may be relatively mature and great at friendship, but that doesn't mean there's nothing left for them to learn. That's something this show should do a lot more of. And it's nice to see the show regaining some consistent charm and humour after the season's rough start. 

Also, I seriously underestimated the impact the school has had on this show. It adds so much context to stuff the show would have tied itself into a pretzel explaining in earlier seasons, and makes it all feel so much more natural. And seeing actual jokes based around Spike's wings proves that this show is capable of direct continuity when it tries. That sense of progress has been the best part of these past few seasons.
