Calculate what I need on my final - Help?

<p>Hey guys. </p>

<p>I take my final in my calculus class on Sunday (I could take it Tuesday or Wednesday if I want, but I want to just get it over with). Right now, I have an 85.8% in the class, and my final is worth 22% of my grade. I was just wondering, is it possible for me to somehow get a B (80%) in the class?</p>

<p>Is there any way to calculate this? I used a formula that my friend recommended, and got that I'd need a 51% on the final, that just doesn't seem right for some reason. </p>

<p>Any help would be greatly appreciated! Thanks!</p>

<p>59.4%. On my phone so I can show you later if necessary. Just a pain to do it here.</p>

<p>(100%-22%) x 85.8% = 0.67</p>

<p>0.80 - 0.67 = 0.13</p>

<p>0.13 / 0.22 = 0.59</p>

<p>You need a 59% to keep your “B”</p>

<p>Just gonna say you should fail for not being able to do this on your own while in a calc class.</p>

<p>You should probably not get it into your head that you can get a 60% and still be fine. Just study hard and do your best.</p>

<p>I agree with RacinReaver</p>

<p>I know it’s basic calculations, and my university has this stupid rule that I had to take a math class for my major, and it’s not actually calculus - it’s Survey of Cal, which is like a baby form of Pre-Cal. </p>

<p>But, can someone just run it by me how I can make a 60% while having an 85 and still have an 80%? How does that work? Realistically, it shouldn’t. (Also, I’m a Poli Sci major, so I’m virtually mathematically illiterate.)</p>

<p>… oh dear. Math in this country. </p>

<p>And reading apparently since it was already laid out in post 3.</p>

<p>How would you feel about a math major saying they’re politically illiterate?</p>

<p>@RacinReaver, I’d say that’s a fair analysis. Everyone has their bane. My friends and I just like to joke that poli sci/liberal arts majors aren’t good at math/science and vice versa. Of course, it’s not always true, but still accurate nonetheless.</p>

<p>First we calculate the “weight” or impact of all your grades, so far, without the final exam grade included. Since the impact of the final is 22%, the impact of the other grades is what is left over → 100% - 22% = 78%</p>

<p>Next we calculate the impact of your current “B” grade:
78% x 85.8% = 0.67</p>

<p>Using that “impact” number (0.67) we can calculate how many more points you need to keep the “B” (“B” is 80% or 0.80):
0.80 - 0.67 = 0.13</p>

<p>But, since the final is only worth 22% (same as 0.22) of the total grade, we have to adjust:
0.13 / 0.22 = 0.59</p>

<p>So you need 0.59 more points which is the same as 59%</p>

<p>Therefore you need a 59% to keep your “B”</p>

<p>Let’s see if you can still get an “A” (90% or 0.90) for the course:</p>

<p>0.90 - 0.67 = 0.23</p>

<p>0.23 / 0.22 = 1.05</p>

<p>You need a 105% to get an “A” which is unlikely unless extra credit is offered…</p>

<p>Thank you, keesh17! I guess that makes sense, and yes - Survey of Cal will be my first and only math class of college! For obvious reasons.</p>

<p>Total Marks = 100</p>

<p>Final Grade worth = 22</p>

<p>Which means you have scored 85% of 78 = 66.3</p>

<p>To score overall 80%, you need to score,</p>

<p>80-66.3=13.7 OUT OF 22</p>

<p>66.3 out of 78 + 13.7 out of 22 = 80 out of 100</p>
