<p>So Chem 130 is a 3 credit course and Chem 125 Lab is a 1 credit course, will each one have their own separate grades on your transcript or do they combine to make one "General Chemistry" grade? </p>
<p>For example if I got a 90% overall in Chem 130 and an 80% in Chem 126 will it become 85%?</p>
<p>Since they are separate classes they are obviously separate grades. Also, your thinking is incorrect by giving two courses with different allotted credit hours equal valuation. I only mention this if you attempt to calculate your GPA. That should be: (4.0 (GP for 90% in Chem 130) *3 + 2.7 (GP for 80% in Chem 125/126) *2)/ Total credit hours. Note the 2 because you are also wrong to say Chem125/126 is only 1 credit hour. You should also consider the fact that the two classes are on different grading scales when an averaging is attempted like you have attempted above.</p>
