Oh boy Youngprer,I know what you are going through. In my 4 years of high school I had 11 english teachers and one entire semester none. In the last year they finally secured one that that didn't suffer a nervous breakdown.

Whole school had to buckle down and catch up.
The school actually failed to meet the education requirements. We had to pass in 5 subjects and 2 electives.
English.. we barely made it
Math the only subject we were any good at... the school produced a lot of accountants.
Science. only one science teacher and he didn't teach my class.
Art... no art teacher
PE... no PE teacher.
Music.. we didnt even have classes for that
They gave us all a passing grade LOL
for electives most did agriculture... I studied an extra subject via correspondance... man it was freezing sitting outside in winter doing my lessons.
Lucky it never snowed in that part of the country but the wind chill factor was about 4 degree celcius just above freezing. The commerce class had the locker room..that was about 6 foot by 6 foot...
Good luck with your studies
