Twelve students are studying Mathematics. They take three tests, each marked out of 100.
The results for the first two tests taken are shown below.
| test 1 | test 2 | |
| Tom | 48 | 53 |
| James | 83 | 86 |
| Alira | 61 | 67 |
| Connor | 73 | 54 |
| Edward | 66 | 59 |
| Heidi | 69 | 78 |
| Jo | 33 | 98 |
| Kai | 88 | 44 |
| Sarah | 100 | 53 |
| Piper | 75 | 78 |
| Layla | 81 | 79 |
| Isabelle | 57 | 65 |
A prize is awarded to the student with the highest combined total score from the three tests. If two students are tied for the highest score, nobody gets the prize.
As the scores currently stand, one student is able to be sure to win this prize as long as a high enough score is achieved in the final test.
