what is the total number of electrons shared in a double covalent bond between two atoms, and why?

four. One covalent bond is two electrons, a double convalent is twice that.

why wouldnt it be 8?

Because 2*2=4.

Reread Bob Pursley's answer. Two electrons is a single bond; therefore, a double bond is twice that or four electrons.

i know, but on my test i have to say why i got it wrong and i put 8, so can i just say its not 8 electrons because it would only be 4?

i know, but on my test i have to write corrections why i got the problem wrong and i put 8, so can i just say its not 8 electrons because it would only be 4?

I have no idea why you got it wrong (except your answer was wrong); that is, I don't know why you picked 8. If you know why you answered 8 then that is what you put down for why you got it wrong. I hope this helps. If not I'll try again.

the thing is i do study, but during tests i freeze up idk why but i jus get rly nervous. :( are there any ways of studying that you find effective that i can posibly try?

I suppose everyone has a favorite. I do the following for a test.

Summarize my notes and equations. Write them down. Then write and rewrite them until I have them memorized. For some tests that works very well. With math tests, it is important that you practice enough before the test that you UNDERSTAND how to work the problems. (You can't memorize all the math problems). That way you can work ANY problem thrown your way and not just the ones you have worked so many times you have them memorized. I hope this helps a little and good luck.
