After completing the kata:

1. No random tests;
2. According to the description, it looks like the Student struct has been created initially; however, to complete the kata, warrior is required to create it by themselves, which is not supposed to be done.

1. Why does the initial solution has function TwoOldestAges() and not UpdateAverageGrade() one?
2. No sample tests; I have a strong suspicion that random tests are missing as well
