We need to know the total points including those for the next test.

Your question is not quite complete.
How many tests gave you that 66.67 average ?
Suppose it was only one test, then you need x on the next so that
(x+66.67)/2 =70
x+66.67 = 140
x = 73.33
If your 66.67 was the average of 5 tests, then if x is your 6th test
(x + 5(66.67)/6 = 70
x + 333.35 = 420
x = 86.65
Can you see the problem with your question ?
