It depends... I highly doubt your next text will be out of 100. But it depends on how much the text is worth.. How many previous tests you had to get to 70.. Heres an example assuming you took 10 tests and got 7/10 on all of them (also assuming they are all worth the same).
Divide that by the number of tests you took (10 in this case) to get your averaged (grade).
Then to calculate in the 100% add that on the end. If you do the calculations right (800 / 11) and your average (or grade) would be 72.727272...% (... means repeating)

we would need to know what percent of your grade that next test counts for

70% + 70% + 70% + 70 + 70% + 70%+70%+ 70% + 70% + 70% = 700%

Depends on how much each test is weighed.
If all tests are weighed equally:
70 % + 100%= 170 / 2(number of tests) = 85% B
And that doesn't take in account homework, and such.
That would depend on how many other grades you have.
