The reading is on'yomi because it's a jukugo word but がく gets shortened to がっ, so be careful. Maybe you just wish the school term would get shorter which is why you shortened がく like that?
I am planning to take Japanese and kimono classes with Fugu next semester as well.
After this term ends, Koichi and Koichiko will have their wedding ceremony in Hawaii.
Final exams are held in March so there's still plenty of time to prepare.
