How this is calculated

The target percent applies to every mark in the course, including the marks you have not taken yet. Subtract what you already earned. What remains is the score you need on the work still left.

marks needed = target% × (marks so far + marks left) − marks earned

  1. 40 of 50, with 50 left and a target of 80%: 0.80 × 100 − 40 = 40. That is 80% of the remaining 50.
  2. 70 of 80, with 20 left and a target of 90%: 0.90 × 100 − 70 = 20. That is a perfect score on the remaining work.
  3. 45 of 50, with 50 left and a target of 70%: 0.70 × 100 − 45 = 25, which is 50% of the remaining work.

If the marks needed are higher than the marks still available, the target is impossible even with a perfect score. The best possible overall is (marks earned + marks left) / (marks so far + marks left).

Marks percentage reports the score you already have. This page says what you still need.

Target grade questions

40 marks out of the remaining 50, which is 80% on that work.

20 out of 20, a perfect score on the remaining work.

You have already passed the target. Even a zero on the remaining work leaves you at or above the percent you entered.

The target is impossible. The best possible overall is shown beside the result. 40 of 50 with only 10 marks left cannot reach 90%, because a perfect finish is 50/60, about 83.333%.

No. It uses your marks and the marks still available. A percentile needs everyone else's scores.
