It depends on how much weight tests have on your grade. Essentially, an A on anything will bring up a grade. However, it may not be significant enough to even matter.
To a 100% A
To calculate your new grade after receiving a 75 on a test, you need to know the weight of the test in relation to your overall grade. Let's assume the test is worth 20% of your total grade. You would calculate the impact of the test by finding 20% of 75, which is 15. Adding 15 points to your current grade would depend on the weight of the test and the rest of your grades in the class.
assuming thats 83% average, then 87% gives an 85% average
study be confident
Yes - it helps you learn the material better by giving you practice, and it gives you an extra grade to help bring up your average
You scored 47.6% on that test. We have no way of knowing what grade the teacher will give for that score. But if it were up to us . . .
Well honey, if you started with a B and then tanked with an F on a test, you're gonna be crying in the corner with a grade of D. That F is gonna drag you down faster than a lead balloon, so buckle up and start studying if you wanna crawl your way back up to that B.

If you have a 2.76 GPA (grade point average), you probably have mostly Cs and low Bs in your classes. It's a good idea to try to bring it up to at least 3.0, which could be achieved with mostly Bs.
You do the best that you can and work your butt off in that class in order to get your grade up. If you flunked that test, there must have been a reason. Figure out what the reason is, and attempt to fix that issue and move on from them. Now, I don't blame you for being freaked out about a D..I've been an all A's student all my life! Talk to your teacher about retaking the test to help bring up your grade. If he or she says no, then be sure to make your best effort on the work in the future to ensure a good grade to boost up that D. It will take a LOT of work unfortunately, but in the end it will be worth it if you worked hard! Also, you could ask for extra credit assignments.
you can catch up on missing assignments, bring up your grade,and work on your achievement goals.
