How do two final-exam scenarios compare for this course?

Enter your current grade and the final's weight once, then two different final scores to compare. The base scenario never changes; only the delta shows what the alternative would do.

How we calculated this

Both scenarios are computed independently from the same current grade and final weight, so the base is never overwritten by the alternative. Using the example values above (88% current, 20% final weight), a 90% final gives 88.4%; a 100% final gives 90.4%, a difference of exactly 2.0 points.

Limitations

This compares exactly two scenarios for the same course structure; it does not account for other work changing at the same time. For a full projection across several remaining pieces, use Can I Reach My Target Grade.

Common mistakes

A common error is changing both the current grade and the final weight between the two scenarios instead of holding everything constant except the one variable you actually want to compare, since that makes the delta reflect two changes at once rather than one clean comparison.

Frequently asked

Why keep a "base" scenario at all?: So you always have a stable reference point. Comparing two moving numbers is harder than comparing one fixed number against one alternative.
Can I compare more than two scenarios?: Recalculate with a new alternative to test another scenario against the same base; each comparison stays independent.
What should I hold constant between the two scenarios?: Everything except the one input you are actually testing, usually the final score; changing current grade or weight at the same time mixes two questions into one answer.
Is the delta always the same regardless of which scenario I call "base"?: The size of the delta is the same either way; only its sign flips depending on which scenario you treat as the starting point.
Can I use this to decide between two exam-prep strategies?: Yes, if each strategy maps to a specific expected final score; the delta shows exactly how much that difference is worth to your course grade.
Does the delta tell me anything about effort required?: No; it only tells you the grade consequence of two outcomes, not how hard either one is to achieve.
