<p>This is going to be very silly but I'm just gonna ask.</p>
<p>Since I'm not so sure of how to calculate over-all GPA, school system does it for us all the time anyways. But now I want to kind of predict how my GPA would be after this semester. I did this calculation and the result actually shocked me quite a bit.</p>
<p>This is what I did, and what I did is likely wrong.</p>
<p>Let's say I have a 3.98 right now( and I've done at least 60 semester units). Currently I'm taking 17 units, and I do not think I can get straight A's for this semester(I'm trying tho). Realistically, maybe I will get 1 B among 4 classes I'm taking now. so (4+4+4+3)/4 =3.75 (approx) 3 of them are 5 units class, one is 4 units. So I just simply did (3.75 +3.98)/2=3.865. I was shocked to see that one B can do so much damage to my GPA. I know I just want to approximate but maybe the way I did the calculation was totally off? I'm not sure, I was hoping the gpa stay above 3.9. </p>
<p>You’re missing a step. You need to also factor in the number of units each class is worth to determine what weight each grade will have on your GPA. A higher unit class will have a bigger impact on your overall GPA than a lower unit class.</p>
<p>The formula is grade points/number of units.</p>
<p>Using the example you gave part 1 (if the B is in a 5-unit class):
Class A is worth 5 units and you receive a B.
Class B is worth 5 units and you receive an A.
Class C is worth 5 unit and you receive a A.
Class D is worth 4 units and you receive an A. Total units: 19 units</p>
<p>Using the example you gave part 2 (if the B is in a 4-unit class):
Class A is worth 5 units and you receive a A.
Class B is worth 5 units and you receive an A.
Class C is worth 5 unit and you receive a A.
Class D is worth 4 units and you receive an B. Total units: 19 units</p>
<p>[Note: Many colleges do not round up your GPA. They will usually cut it off at either the second or third decimal place. This can make minute, but noticeable differences in your GPA.]</p>
<p>To determine the impact on your current GPA, you would need to know the number of grade points from those 60 units you have already completed. It’s the same process: add all grade points together, add all units together, and then divide the total number of grade points by the total number of units.</p>
<p>You could also just google “GPA calculator” if you wanted to do it the lazy way ;)</p>
<p>EDIT: I just noticed something… you say you’re taking 17 units, but the number of units/classes you indicated does add up to 19 units. That will also make a difference making sure you have the right number of units for your classes involved in your calculations :)</p>
<p>Sorry! Actually I made a mistake. for the 4 classes I’m taking now 2 of them are 5 units (chem and physics), one is 4 units (c++), one is actually only 3 units (linear algebra), so adds up to 17 units!! sorry about the confusion. I’m worrying about not getting an A in chem( this is really upsetting, because chem 1A is actually not even a difficult class compared to many of the math and physics courses, but this professor is just really making me struggle). </p>
<p>Thanks for your explanation! U know what, I’m just going to use a GPA calculator to save me some brain cells. hehe! Thanks!@</p>
