Before you assume I’m some generic student complaining about how bad I feel these teachers are, I want to mention that our board of education also found these teachers bad.
There are three specific teachers whose classes I had done bad in, and the years after I had them, they were fired from the school by administration for poor teaching and poor academic instruction.
These teachers were on their first and/or second years of teaching (with one straight from India!)
I’m not a lazy student, and I am not brewing up some self-serving bias here.
I just want to know how I can explain these to colleges.
Also, if there is any way I can perhaps get something done about these grades.
Suggestions please?
You probably shouldn’t but maybe the letter from your guidance counselor could put the teachers into context.
You could maybe retake the classes online or something for grade forgiveness.
You should not mention this, however, your guidance counselor should in their recommendation.
If you mention it, it will seem like you’re that jerk who always blames other people for your problems 
Try to talk it through with your guidance counselor. He or she probably knows what to do in a situation like this more than any of us do.
You’ll have lousy teachers who are barely comprehensible in college too. What this complaint says is most likely you’re overly reliant on their instruction and unable to make adjustments and find the help you need elsewhere. In college this means finding a tutor, whatever it takes.
Unless your teacher was directly sabotaging your grades, i wouldn’t even go there.
I definitely think it should be addressed, but by your GC and not you. It looks as if you’re complaining if you say it. If your GC says it, then colleges will understand since your GC knows the academic area.
