Who's side would you take in this problem?

So I took my final exam for history. The test was ok in difficulty, I had a C in that class and with at least a B in the exam, my final grade would be at least a B+. Here's the problem, I didn't finish the test and my teacher never told me I couldn't finish it so I end up missing automatically 35 questions out of 200. Throughout the school year, my teacher would always let his students finish tests after school, but this time, the biggest test of the year, he gives me a time limit when he never announced it. I had 2 hours to finish 200 questions, for people who thoroughly read questions and answers, that's too little time. And this conflict escalates to the school too cause the school sets the final exam dates. My final exam date was the last day of freaking school so there was no chance to finish the test since teachers had to turn in grades immediately. Unlike the school I am in now, my old school did the exams 1 week before school ends so that if you don't finish, you have plenty of time to finish afterwards, that's not fair. Plus, teachers actually encourage you to take your time in tests, not to rush, and to carefully read each question and answer, yet, my teacher says that and gives me a huge test with very little time. So basically my best score can a 165 out of 200, which is bad and I know I didn't do too well. You should never have to be timed for huge final exams, we should always take our time cause that can affect my career after high school. I mean, who knows? Maybe now I can't accepted by some colleges now since I don't have A's and B's now. What do you think?
