Math question. What do I need to get an A?
920727
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.

I think you can just add up your grades per points.  Each one should have a point value such as A- would be around 3.5 or something.  Usually like this A=4, B=3, C=2, D=1 and F=I guess Zero.  \nSO if say you got three A's, two B's and one C it would go something like this:\n4+4+4+3+3+2=20  divide that by the number of numbers  which is 6/20 and you get: 3.3 grade average.  \nI think that is how I used to do it in college.  But for the minuses and pluses like A+ or something...I don't know.  Just ask your school administrator what the point value of each grade is and then follow that solution I gave you. \nGood luck!\nd.\n\nthen again, your school should be doing this for you, when you get your grade report!!

Typically, entrance requirements state that Algebra 2 (graphing, linear equations, rational equations, quadratics, logarithms, etc. although Precalculus would be better), and previous chemistry classes in high school should suffice.  You may need to take a science placement test.  But not all colleges require that.

The answer is C.\n\nHowever, do you know how to get the answer?\n\nThe mean is the average of all of the numbers. Add the four numbers you gave me and divide by 4. That is how you get your number. This is what teachers use to find your average for your school grade.\n\nSorry, im studying to be a teacher, I wanted to make sure you understood.

bring the a's to one side... u then get 9a = 27 ... divide and answer is a = 3

Get Straight A's\nHave extra curriculars\nBe a good person\nBe a genuine person whose personality they can see\nWrite a good entrance essay that shows who you are\n\nAll else fails having a lot of money helps.

According to the College Board, you'll need a 500 - 610 on the verbal and 530 - 650 on the math. At least, that's what the mid- 50% scores are.

This is your Grade Point Average. Most schools use a A-,A,A+ scale. For example, if you get a 98 in Calculus, you would earn an A+ which is worth 4.33 points multiplied by how many hours of credit you get for that class (probably either 3 or 4). Add up all of your hours multiplied by their value and then divide by the total hours you took and you'll get your GPA. \nA+=4.33\nA=4\nA-=3.66\nB+=3.33\nB=3\nB-=2.66\nC+=2.33\nC=2\nC-=1.66\n\nFor example:\n\n3 hours Math 98=A+ ==3*4.33= 13 points\n4 hours Science 80=B- ==4*2.66= 10.64 points\n3 hours Chemistry 95=A ==3*4= 12 points\n1 hour PE 75=C ==1*2= 2 points\n4 hours Physics 88=B+ ==4*3.33= 13.32 points\n\nTotal Points: 50.96\nTotal Hours: 15\nGPA: 50.96/15 = 3.397

Most BA programs require math skills at least to a basic algebra level.  This is needed to support the core statistics and finance classes.  Advanced mathematics is typically not required; although, I believe that it should be.

b-a, at least if it is mathematics

Please, learn arithmetic.\n\n12

since no one else will explain it, if u have 7a-5<9. then u have to add five to both sides to get rid of it on the left side. so that makes 7a<14. then to get a by it self, u have to divide both sides by 7. so u get a<2.

You need to know the equivalent of A, B, C, D, F, which will depend on what country you are in (and different US school systems interpret grades from other countries differently, alas.)\nIf you receive the same letter grades,\nA=4\nB=3\nC=2\nD=1\nF=0\nAdd up your grades and divide by the number of courses.\nYou can also use the 12-scale (a+=12 down to F=0), figure it out that way and then divide by four.  Little more accurate, little more work.\nSo if you had 5 classes, 1 A, 3 Bs and 1 C, your total would be 15, divided by 5 =3, GPA is 3.0

If you got a B+, then all you should need to get is an A- to get in the 'A' family - the upward trend should show you improved over the term. Other than doing extra credit (as you noted), I'd cover those things that gave you trouble and find a different way to learn them - maybe use some flash cards for vocabulary terms. But strive for your "usual" A+ this term to give yourself a buffer.\n\nBut you didn't provide any other specifics - what specific branch of science are you learning? Are you comfortable in the lab? If you're taking chemistry, you will want to be adept at algebra for problem solving and balancing chemical equations. If you're taking physics, you'll need to know some geometry and trigonometry (as well as some algebra) for force and trajectory problems. But if you're still calling it by the generic name "science," then that tells me you're probably in junior high - at least you have some fair warning for high school science classes.\n\nOverall, though, don't get overly concerned about your grades - it's more important to *learn* something that you can take out of these classes. If you get an occasional B or B+ but learn a lot, you're going to have an easier time in college than those who work just to get A's.

3.5 or higher is usually needed.  3.8 and up is best.  Sometimes students with 3.0s get in, but not that often.

Obviously his school uses a minus system if he has the potential to get an A-. \n\nIs this college or high school? I will assume college since this is the college board. It also depends on the credit hours of each class\n\nSystems that use both plus and minus grades usually assign an additoinal 0.30 points for + and subtract 0.3 points for -. Thus, an A- should be around a 3.7 and a B+ would be a 3.30.\n\nPoint Value * Credit hours = GP\nSum up your GP and divide by the sum of your credit hours and that is your GPA.\n\n4.0 * 3 = 12\n3.7 * 3 = 11.1\n3.0 * 3 = 9\n\n12+11.1+9 = 32.1\n32.1/9 = 3.57

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.
