I hate my band teacher?

I'm in grade 11, and my band teacher seems to think that we are just little music majors or something. He's new this year, and he started out by having us play 12 major scales and their minor equivalents in harmonic, melodic and natural forms, dorian scales, diminished scaled, pentatonic scales and aeolian scales individual in front of the whole ensemble of fifty. We haven't ever been taught those things, we are in high school. Then he made us select a solo piece to play, individually. We used to have band in one block during the school day that lasted all year, alternating each day with english( he have four blocks each semester, and two semester in a year, that's only 8 blocks)and one morning before school rehearsal, and one after school rehearsal. Now we have 3 morning rehearsals, 2 after school rehearsal, and two lunch time rehearsals in a week. He gave us music that's WAY harder than last year and says things like 'If you can't play this perfectly by next week, you aren't good enough to play at this level and you should drop this cl'. We are in high school, some of us are in the band program because we enjoy music, but he sucks the fun out of it. What should I do?
