can someone calculate my grade for me?

This entirely depends on the number of tests you've had this term. Let me break it down for you:

If this is your 2nd test you need a 58.32.

If this is your 3rd test you need a 70.98.

If this is your 4th test you need an 83.64.

If this is your 5th test you need a 96.3.

If this is your 6th test or more, it is impossible to bring your grade up that high.

You need 5.7 points more to get to the 59.5. Right now, your test average is 14.85/45 (that's the same as 33/100). You need to add the 5.7 points to those original points. That brings 14.85 up to 20.55 (that's the same as 45.66/100). Your test average must be 45.66.

with a average test grade of 33% thats means you only aquired 14.85% of a possible 45%... i would say anything less then a 90 on that test wont do much for your final grade... in order to really calculate i would need to know how many test you have taken..

my grade is 53.8 and the quizzes 25 % what is my grade
