i got a 100 on my science unit test......?

Question

so my average was a 92 before (not so good for me) but i got a 100 on my science unit test so how much do u think my grade will go up?
& i know you can't be exact cause you don't know how many points the test was worth and i don't either, but it was a unit test.... there were a little less than 50 questions.... so how much do you think it will go up?

Answer 1

To figure it out all you have to do is...

Multiply your score by what percent of your grade it will be, and then add it to your current average multiplied by 100% minus that percent.



For example, if you wanted to figure out your average if the exam was worth 20% of your grade this is what you would do...



(100 x .20) + (92 x (1.00-.20)) = 93.6



Asumming the exam is a quarter of your grade you woudl have a 94 average.



30 percent of your grade would be a 94.4



50 percent would be a 96

Answer 2

How many other tests did you have? I'm sure your grade would go up to 94 or higher.



Great work on your part!
