If i get a 70 on a test, would my grade go up or down

Could go both ways.

Step-by-step explanation:

It all comes down to the overall grades you make on test and those all calculate together. Also, tests could count for more of your grade if your teacher makes it, example is at my school tests count for 20% of my grade which if I made a 70 my grade would most likely go down a bit.

That depends on the number of points for each question. If there are 7 questions and each question is 10 points, you would get 70 points, boosting your grade unlike there being 20 questions each worth 5 points, then your grade will go down.
