What's your target grade?

I messed up before, sorry it is 

86% is only (100-20)% of your grade at the moment 

Final grade = Grade times weight 
Final grade = (0.86 * 80) + (grade * 20) 

so for example, if you get a 53% on your final 
your final grade would be 
= (0.86 * 80) + (0.53 * 20)

Stealing @jigglypuff314 's math:
Final grade = (86 * 0.80) + (grade * 0.20)
Turn it around to get your targets:
test_target_grade = 5*(final_target_grade-68.8)
If you can put the formula in a spreadsheet, it tells you all sorts of interesting stuff.
What I find most interesting is that you need 106 on the exam to get 90 for the course (so an A looks out of the question), but B+ is still achievable!  Do your best!
