clover solution, i don't remember we can access to a char by charAt(), i always used it but i don't know how i forgot that. thanks for a new short way to solution.

it works only if the full name is in the format . If it is <LastName, FirstName>, it will not work.

Is this faster?

If score is "10:9" this function will break.

This is a great way to practice Duration class methods. Very well done.

thanks!

amazing @adrian-lui

i mean, yeah, but the task specifically asks you to include your points when calculating the class averange :p

I thought that this function would expect points as the return statement..can somebody explain to me why not?

You can make the isPrime method much more efficient by only checking against other prime numbers under p. Since you are building up the prime cache starting from 2 and working your way up there is no risk of missing primes.

I missed that the upper bound was Math.sqrt in my solution.

Adding yourPoints to the array will NOT change the result, if you think about it. It will change the average point but it will not change the fact that you are higher or lower than the average.
