What score do you need on the final exam to hit your target grade?
Your current grade counts for the rest of the grade (100 minus the final exam weight).
Take your desired grade, subtract your current grade times the part of the grade that is not the final, then divide by the final exam weight. For example, with a current grade of 85 percent, a desired grade of 90 percent, and a 30 percent final, you need 101.67 percent on the final.
Then the target grade is not reachable even with a perfect final exam score. The calculator says so plainly instead of hiding it. Your options are to aim for a slightly lower target grade, or to raise your current grade with remaining coursework before the final.
Then you have already secured your desired grade: even a zero on the final keeps you at or above the target. You can still take the final to protect your grade or to aim higher.
