Well I really think its right for you to be able to make those assumptions because I'm willing to bet you've never had him as a teacher. And if you did have him as a teacher, you would no that he never told you what you wanted. And I am not even complaining about that. I am talking the laziness in the school system and I think it is getting worse every year.
what about taking points off for things you do not agree with and mostly in formatting stuff that you not expecting it still GET USE TO IT. because it does get worse.
If you think it is bad now wait until college you will truly deal with teacher who do not care and they are the one you start to hate. I have had some hard teachers who have rip in to me for stupid mistake and hell even once was the the one who was rip into in front of the entire class because I blank out on a simple formal and he was kind of tick off. Get use to it. You have not seen anything yet.
Also all the complaining about everything wrong with every single teacher leads me to believe the simple fact that it is not as bad as you say it is and most of the teachers are good. I sorry but the odds that you have almost all your teachers being crap are well next to zero.
That and you seem to think it is bad now how your teachers are. You are in for a true rude awakening in college because it only get worse. Particlle your first 2 years. A lot of the professor try to keep their students at bay and really do not care about them because chance are good they will not see you after that. Now after you become an upperclassmen they treat you a lot better in college because you made it past the weed out classes and are more than likely going to complete you degree. You just seen nothing yet. Just remember it will be a lot worse for you in a few years if you think it is bad now.
Think back when I was in HS I remember teachers I though where crap back then and by the end of that school year or now I think they were great teachers because I have gain new respect though college or I found out what they put me though really did prepare me for what I was going to be facing.
