Can you at least guess what my grade average will be?

So, I don't think that i'm doing very well in math. We have only had three quizzes so far, and I got a 77, 71, and a 75. I usually get very good grades, so I am very nervous. I always do my homework and participate. Can you somehow at least guess what my average will be for this term?|||Quizzes are probably all worth the same amount of your grade, so if that's all you have graded so far, add them up and divide by 3 to find your average.
