I don't understand. My GPA won't go up?

<p>I currently have a 2.85 GPA. I have 24 credits earned, and 68.5 grade points earned. I'm taking 3 classes this semester and am trying to get straight B's. But I calculated what my GPA will be if I get B's, and my GPA will stay the same! I'll only have a 2.89 GPA.
I don't understand. I would think getting B's would bring up your GPA, not keep it the same.
Is this correct? I'm really confused.</p>

<p>depends what you’re average is. it’s pretty hard for 3 classes to raise your gpa, if the starting point is even relatively decent (as 2.85 is) if you get straight b’s. especially if you’re deep into your highschool career</p>

<p>GPAs are difficult to raise from 2.85, unless you have many A’s. Since B’s are only 3.0s, they do not have the push that 4.0s (A’s) do.</p>

<p>So the only way I will be able to raise my GPA is to get only A’s? And I’m in college.</p>

<p>The more credits you have, the less effect one more course has on your gpa, so the harder it becomes to raise your gpa. </p>

<p>For example, suppose you had 100 credits and a gpa of 2.85, which would mean you had 285 quality points earned. If you took three more 3 credit courses and got B’s and 9 quality points, you would have 294/103 = 2.854 gpa. Even if you got 3 A’s, you would have 297/103 = 2.883 gpa.</p>
