First of all, I should tell you that the teacher was really unprofessional in her comments to you -- if she was being tested on maturity and professionalism, she'd test at a very low level.\n\nNow, on to your question.  I don't know what grade level you're at (I'm guessing high school?).  If so, you need to talk to a school counselor and explain your problem.  If you really do have an academic problem, the counselor will have the resources to help you with that.  Also, you could check to see if anyone would be willing to do some tutoring.  If you don't have the financial resources to pay for a tutor, maybe you could work something out with someone, like doing favors or chores in exchange for the tutoring.  \n\nThe most important thing is not to feel ashamed if you have a problem.  That teacher's comments said more about HER character than about YOU.  If you do have a problem, seeking help for it is really admirable.  I wish you the very best of luck!

Go to a teacher to show you more cases, and try to work harder!

The silver_fox sounds as if he may have a winner; however, this methodology would tend to get you a bad score for your paper.  \nLet tham be and work hard on your own answers because the teachers will not be fooled for long.  Jose

See if this table will help. If not, you may just have to go back to where your textbook covers that or ask your teacher to explain.

You should face him either before or after class and explain that you don't feel he is explaining enough or giving enough examples in class. Ask him what the check mark means. If he tells you it is because he looked at the paper, you want to know if it was a good paper or not. Tell him you are trying to improve and can not do it with a check mark. Don't be affraid to talk to teachers.

I would say get ur proffessor or teacher to tell u that. They are trained to explain things.

How is everyone else doing in the class? I have heard of teachers that grade really hard and then curve a lot at the end of the year. So a %50 turns into an A grade.\nI suggest talking to the teacher and seeing what the teacher has to say.\nAlways-> If you are doing badly in a class you should always go to the teachers office hours. If a teacher knows you and knows that you are trying, they are more likely to give you a better grade. Even if you aren't doing badly, go to the teacher's office hours! There is a big difference between a B+ and an A-.\nConsider a tutor. Some colleges have free tutoring!!! Use all of your college resources, you are paying for it.\nIf you can still withdraw/drop from the class you should consider doing that. Don't just quit going if you can't drop the class!! If you can't drop or withdraw from the class formally with your registrar’s office then continue to show up if you have to retake the class. The more you learn now the better it will be the next time you take the class. \nBeware if you don't drop or withdraw the class officially, many schools, if you are retaking a class will average the two scores together. So if you get a 1.00 this time and an 4.00 (A) next time your overall grade is considered to be a 2.5. \nAs for Financial aid depends on the school. Many schools will give you one semester to mess up. They will consider you on probation and take action if you don't improve. \nAlso if you drop the class you could lose some financial aid and have to pay whatever the school makes you pay for a late drop out of your pocket.\nSee a Financial Aid counselor.

Given the results of the two tests are 90% and 84%, we are interested to have a result in the third test such that the average of these three (3) tests will fall under the range of A. That is:\n\nLet x be the result of the third test in percentage. So we have,\nAVERAGE = (90% + 84% + x) / 3.\n\nSince A lies within the range of 90% to 100%, we want the average to lie on this range. That is, \n90% <= AVERAGE <= 100%.\n\nCase 1: 90% <= AVERAGE\n\nIf the target grade is the lower bound of A, that is 90%, then we have the following:\n90% <= (90% + 84% + x%) / 3\n270% <= 90% + 84% + x\nx <= 270% - 90% - 84%\nx <= 96%.\n\nThus, you have to obtain a score of at least 96% to get a grade of A in the class.\n\nCase 2: AVERAGE <= 100\n\nIf the target grade is the upper bound of A, that is 100%, then we have the following:\n100% <= (90% + 84% + x%) / 3\n300% <= 90% + 84% + x\nx <= 300% - 90% - 84%\nx <= 126%.\n\nThus, you have to obtain a score of at most 126% to get a grade of A in the class.\n\nCombining these two results, we have 96% <= x <= 126%. That means, your score in the third test must ranged from 96% to 126% to obtain a grade of A in the class.\n\nNote that in some instances that a student's grade in a test can exceed 100% whenever the student answered correctly the  bonus item(s) (commonly a very tough item) given by the teacher (or professor) in a test.

the average, IE add up all parts and then divide by the number of parts.  For example if you'd taken 3 tests and gotten a 70 on the first, an 80 on the second and a 90 on the third you add the three to get 240, and then divide by 3 and your mean grade is 80.

2.0...a D is worth 1.0 and a B is worth 3.0...average them together and you get a 2.0

If your current grade is 75%, that includes your 72.2% average (add your 5 tests, 361/5) from tests and your good homeworks, etc.\n\nYou need a 75% to meet your needs. So you need to study to improve your odds.\n\nNow, if you wanted to get technical, we could figure out the standard deviation... and then see how many standard deviations 75% is above the average; but, even if I knew that, I'm not very good at figuring out the percentage distribution above average that would be.  But, let's give it a shot.\n\nvariance = sum(x-average)^2/n \n         = (sum(x^2) - 2n*average^2 + average^2)/n\n         = (sum(x^2) + (-2n + n)*average^2) / n\n         = (27517 + (-5)*72.2^2) / 5\n         = 1452.8 / 5\n         = 290.56\nstd. dev. = sqrt(variance) = 17.04582\n\n66% of your tests might fall in 72.2 +/- 17 (55..89)\n95% of your tests might fall in 72.2 +/- 17*2 (38..102)\nthat's just the oddity of std. dev.'s, so pardon :)\n\nso, 2.8 (75-72.2) is 0.1642631 (2.8/17.04582) std. dev. above which is probably just past the average, so it's well below the 83% (1 std dev above)and slightly above 50% (0 std dev).  Even if it was 0.1642.. of (83%-50%) then that's about 56.6%  So study hard, and you're get above your average quite a bit.  If you don't study, you'll fall below.  Good luck.

I don't know what kind of random hits your teacher is making on the students.  Perhaps you can't get past that?  I went to three universities and graduated with a 4.0 GPA in all.  The key to my good grades was my note taking.  I took amazing notes and then when I got home, I went through them and outlined my notes making more sense of them.  By the time I got through outlining and making a really nice bunch of note pages, I knew the material.  It helps to not be freaked out by tests as well.  They never bothered me.  You either know it or you don't.  I think trying to study at the last minute outside the classroom door is foolish.  All that can do is get you all nervous and confused.  Even being around other students who are panicking over their last minute studying will have a negative effect on you.  I stayed away from the classroom and those students until the very last minute and didn't crack a book before the test.  Like I said, "If I didn't know it when I got there, I wasn't going to learn it in 5 minutes!"  I also helped other students study for their exams (the same ones I was taking) and this also solidified the information in my brain.  In that case, you give and you get something in return.  If there was an area which was extremely difficult to grasp onto, I stayed after class and talked to the instructor or made use of the computer programs available for that particular subject.  Good grades take hard work.  Your grades to date are not to be sneezed at, so don't be so hard on yourself.

ask them nicely to demonstrate for you, so that you get a better idea of what exactly they want from you. if they can't, i don't think they have a clue what teaching is about. if they do a good job, then just copy it.

Well if these are scores off an assignment or test and the score is out of 100, then\n\n94 = A (Very Good)\n85 = B (Good)\n85 = B (Good)\n81 = B- (Fairly Good)\n73 = C (Fair)\n\nTotal average out to 83.6 = B. For 6th grade you did very well, so be proud. You are on the right track so far.

You'll make more money per student. \n\nAssuming you actually are good at teaching and know what you are talking about, you can probably charge any Joe off the street $20 per hour-long class, which would give you $200 per hour.\n\nHowever, it's smarter to try to get companies to send you people. If you can get a company to pay for it, charge $50 per hour.\n\nIf you create collateral, such as manuals, charge for it; do  not give collateral away, even if it's a single sheet of paper. Consider a dime a page a minimum price; if you give them a 50-page book, charge at least $5 for it. Personally, I'd charge 25 cents per page; remember, when you give them the answers in printed form, you've killed invoicable follow-up, so you want your blood money now.

Pay attention in class. Jot down what you don't understand and ask them later if timer permits. Also, listen carefully if the teacher already answered one of your questions.
