i failed my chemistry test I got a 11% on it, but then i got an 83% on my assignment. My termwork is worth 70% ( tests and assignements), and then my exam is worth 30%. I only 3 units tests left, and couple assignement and my exam. My first question is what is hypothetically my grade right now ? What do I need on my next projects and tests and exam to finish the class with an 85% or 90%?
To calculate your current grade, you can use the following formula:
Current Grade = (Test 1 + Test 2 + Test 3 + Assignment 1 + Assignment 2 + Assignment 3 + Assignment 4 + Current grade on term work)/7
Plugging in the numbers you gave:
Current Grade = (11 + 83)/2 = 47%
To calculate what you need on your remaining assignments, tests, and exam to finish with an 85% or 90%, you can use the formula:
Final Grade = (Current Grade x 0.70) + (Final Exam Grade x 0.30)
We will calculate the grades needed to finish with an 85% and 90%.
For an 85%:
85 = (0.47 x 0.70) + (Final Exam Grade x 0.30)
85 = 0.329 + (Final Exam Grade x 0.30)
Final Exam Grade = (85 - 0.329)/0.30
Final Exam Grade = 281.57
For a 90%:
90 = (0.47 x 0.70) + (Final Exam Grade x 0.30)
90 = 0.329 + (Final Exam Grade x 0.30)
Final Exam Grade = (90 - 0.329)/0.30
Final Exam Grade = 298.57
Therefore, you would need to score at least 281.57% on your final exam to finish with an 85% and at least 298.57% to finish with a 90%. These scores are not realistically achievable, so it may be better to focus on improving your current grade through your remaining assignments and tests.
