So it dropped my grade to a 68.41%. I have a part 2 final in the same class on Wednesday. A written exam that has 50 questions that is 10% of our grade.

What grade do I need to get a 70% in the class! I definitely learned my lesson this semester! Never take 4 classes when you have TWO part time jobs. In this class I used have an A! smh
I hope this isn't a math related class.

If you actually do need a 70 (that is, professors enter letter grades rather than number grades into the computer), you'll need 84.3.

Here's the math:

For a 69.5:

your current average - 68.41 X .9 = 61.57. So you'll need 7.93 more points to bring your average up to 69.5. A test grade of 79.3 would give you the final 10% (7.93) you need to earn a 69.5.

If you actually need at 70 average, you'll need an 84.3 on the last test that comprises 10% of your grade.

But yes, go in and talk to your professor and explain that you blew the 20% question. If you've had regular attendance and have put in effort, it's likely you'll get some mercy.
How did you determine the highlighted part above?

If the grading scheme is explained in the syllabus, and the student knows the scores of all of their assignments, a grade calculation like this is a trivial exercise, and the necessary math was learned in middle school. Students, especially college students, need to be doing this on their own.

It's an assumption that the score will be rounded to the nearest whole number, or that the instructor will be merciful.

Why would there be that assumption? Rounding a 69.5 to 70 just because is as ridiculous as rounding from a 70 to a 69.5, just because.

Based on having that experience with one of my kids. The system of turning in student grades required the teacher to enter the numerical grades and the "weight" of each assignment, and the computer does the rest. The teacher doesn't enter the final grade - the computer calculates and if the final average is 69.5, the computer rounds it up to 70. Not the best way to pass algebra, but a 69. 5 in that situation was passing.

In some cases I think the teacher does all the calculating and then only turns in the final letter or number grade, which in my opinion is how it should be. If a student was conscientious, and appeared to have mastered the content but had a horrible final grade due to messing up on a question, it seems the professor should have some ability to over ride the numerical grading system.

In my 22 years of teaching, that's how it's always been done. I can't imagine a computer system that automatically rounds up. It might work in an elementary or secondary school, but in a university, professors wouldn't stand for it.
