Study ROI Calculator
See the score you need on your remaining work in each course, and which course has the most marks left to gain. Free, no sign-up.
How it works
- 1
Add your courses
Enter each course and your marks so far, as one average or piece by piece.
- 2
Choose a target grade
Pick a grading scale, or type your own grade boundaries, then choose the grade you want.
- 3
See where to focus
The calculator shows the score you need on the remaining work in each course, and which course has the most marks left.
Example: 60% of a course is marked, and your average is 62%.
- You have already banked 37.2 points of your final grade (62% of 60).
- To finish on 60, you need 22.8 of the remaining 40 points: 57% on the remaining work.
- To finish on 70, you need 32.8 of those 40 points: 82% on the remaining work.
- Each 1% more on the remaining work adds 0.4 points. The most you can finish on is 77.2.
Frequently asked questions
How does the calculator work out the score I need?
It multiplies your average by the share of the course already marked to get the points you've banked. The score you need is the points still missing for your target grade, divided by the share of the course left to mark.
What does secured mean?
You reach your target grade even if you score 0 on the remaining work. Some courses also set a minimum mark for the exam itself, so check your course rules first.
What does out of reach mean?
Even full marks on the remaining work would leave you short of that grade. The table under each course shows which grades are still possible.
Why doesn't it say how many marks an hour of study is worth?
Study time doesn't turn into marks at a fixed rate. In one study of college students, the time spent studying only predicted grades once the quality of the study and earlier grades were taken into account (Plant, Ericsson, Hill and Asberg, 2005). You can add your own estimate for a course.
What's the best way to use extra study time?
Test yourself, and spread your study over several days. A review of ten study techniques rated practice testing and spaced study as high utility, and rereading and highlighting as low utility (Dunlosky and colleagues, 2013).
