Question

What do I need to do to get on my next test to raise my grade to a C?

Answer 1

So I have a 62% in my math class right now. I have a quiz coming up and a midterm (I'm pretty sure it'll count as two tests). What do I need to do to raise my grade from a D to a C in terms of my grades on the quiz and the midterm?

Answer 2

hi @whpalmer4 could you help me out for a sec?

Answer 3

sounds like an algebra question

Answer 4

or @satellite73 it's really nice you guys are viewing this lol

Answer 5

should i go over there?

Answer 6

Possibly. We need to know a bit more about how the grades are calculated.

Answer 7

ok, what would you guys need to know?

Answer 8

Is 70% the cutoff for a C?

Answer 9

yes

Answer 10

Okay, then you need to get enough points on the test such that your total points / the maximum points possible is at least 70%.

Answer 11

my quizzes are worth 30% and my tests are wroth 50% if that helps

Answer 12

ok..how do i figure that out

Answer 13

oh do you need the total # of points I have in the class now?

Answer 14

Well, that's the total of your grade, right? 30% of the grade is quizzes, and 50% is tests. That doesn't quite tell us the whole story, because we don't know how many quizzes and tests there are.

Answer 15

so I should add up all the points I have now and then all of the 100s they're out of

Answer 16

Yeah, you need the total points you have now, and the total points possible up through the test.

Answer 17

up through the midterm?

Answer 18

You mentioned that 30% is quizzes and 50% is tests — what makes up the other 20%?

Answer 19

the points i have now are 594, lemme see how many total there are

Answer 20

daily activities

Answer 21

900

Answer 22

And does that include the "daily activities" points?

Answer 23

yes sir

Answer 24

Can you tell me how many points from each of the 3 categories?

Answer 25

ok so in tests, i have a total of 118 points out of 300. in quizzes, i have 76 points out of 100. however, im going to take a quiz i missed last week tomorrow (which would make the 900 ->1000 but i didn't add it in since it's in as an X right now, which means it's not even totaled into my grade). and then my daily activities are 300 points out of 300.

Answer 26

so if I'm understanding correctly, you have
\[50\%*\frac{118}{300} + 30\%*\frac{76}{100}+20\%*\frac{300}{300} = 62.4667%\]

Answer 27

yes

Answer 28

And you will retake a quiz worth 100 points? That will make the middle fraction \[30\%*\frac{(76+x)}{200}\]where \(x\) is the number of points you get on the quiz. If you get 100 points on the quiz, that will pull you up to 66.0667%

Answer 29

Do you have any more opportunities for points coming up? You said there's a midterm which you think is worth 2 tests? Would be 200 points?

Answer 30

yup

Answer 31

that was factored into the 900 points...

Answer 32

is what you're saying there's no way for me to get a C at this point?

Answer 33

I'm confused — you say you have 118/300 on tests so far. Do those 300 points include this upcoming midterm?

Answer 34

no

Answer 35

wait so then it would be 500 including the 200 points from the midterm

Answer 36

so when you take the midterm, you will have 118 + hopefully 200 out of 500 points for test scores

Answer 37

yea i think

Answer 38

Well, if that is true, the expression becomes

\[50\%*\frac{M+118}{500} + 30\%*\frac{76+Q}{200} + 20\%*\frac{300}{300}\]where \(M\) is the number of points (out of 200) you get on the midterm, and \(Q\) is the number of points (out of 100) you get on the quiz.

Answer 39

ok..so could we possibly say that i get an 80 on the midterm, however many points that is, and an 85 on the quiz? what would we do then?

Answer 40

wait so it would be 118 + 80 so 298/500 and then 76+85 = 161/200

Answer 41

Okay, if you get 80% on the midterm, that's 80%*200 points = 160 points
85% on the quiz is 85%*100 points = 85 points

Close, you forgot that the midterm counts as two tests...

Answer 42

oh riiight ok

Answer 43

ok so then um what would my final grade be :)

Answer 44

Your grade would be 71.95% if you did that

Answer 45

really? omg that's great. i mean it's not an A but it's semi-passing

Answer 46

Because the midterm has a bigger percentage of the grade, if it comes down to getting an extra percent or two on the midterm or on the quiz, the midterm is going to help you more.

Answer 47

ok well, thank you soo much, I really appreciate it! I'll be in and out of here tonight so that's why you'll probably see me lurking lol. Have a nice night!
