This will determine that I couldwhether/if I pass this class. This will determine whether/if I pass this class.

You don't really need a second verb. "whether" sounds more neutral to me. It just states a fact: "This will determine whether I pass this class." "if" shows uncertainty in my opinion: It focuses on how important the essay is for you, and makes the reader think about the possibility that you may not pass: "This will determine if I pass this class."

I do not want to write a long sentence anymore, except this one that I'm writing now. I do not want to write a long sentence anymore--except this one that I'm writing now. I do not want to write a long sentence anymore, except this one that I'm writing now. I do not want to write a long sentence anymore--except this one that I'm writing now.

This is actually a very clever sentence. I suggest two ways of punctuating it to separate the negative and positive statements. You could also reword the sentence: "I do not want to write long sentences anymore, except this one that I'm writing now." "I do not want to write long sentences anymore--except this one that I'm writing now." This version reminds the reader that you had to write a whole essay, and it probably had a lot of long sentences in it. I personally prefer the dash -- between the two clauses because it makes the contrast stronger.

I do not want to write any more long sentence anymores, except this one that I'm writing now. I do not want to write any more long sentences, except this one that I'm writing now.

Another alternative: “I do not want to write another long sentence, except….”
