There seems to be a problem with the test for the alphabetical order of the winners... "Matthew" does not come before "Elizabeth" in case both have the same points.

Did you use the variable for the saved money per month? I used a the fixed amount of 1000$ in the beginning which led to the same failures.

Thanks for this comment! I have been able to resolve the kata thanks to you! :)

Test cases missing, you've to put your solution as the final answer without using test cases. Had the same problem and didn't get any points.

Had a right answer in Python and pressed 'Sample Test Cases'... didn't work. Didn't realize I have to upload it as a final version right at the beginning. So I didn't get any points, because I thought I made some misstakes and looked up the solutions. And there it was....
So please add just one test case to prevent missunderstanding.

As mentioned by SeeFoEv, still a problem as of Feb 23rd 2017. Should be corrected - can confuse beginning programmers.

ooooOOOOOOoooh, man I was wondering what the hell they were smoking betwee that first equation and the second. Thanks.

Thanx, nice solution!

As far as I know 1.(N + 1)^2 doesn't show a decimal separation:-)

I've to mention that the formula which is higlighted in green is missleading.

Especially the second box. It reads like the dot is meant for decimal separation but is meant to be a multiply sign.

I was getting that error due to value of PI.
Thanks for the kata.

Took me a while to get the correct rounding rule. Tried decimal format and it didn't work etc... THX for the kata.

The formula for kinetic energy possesses the expression 'v* *2' and the formula which combines W and E uses 'v * v'. Please use only one of those expressions. Same for '9.81 m/s/s' should be '9.81 m/(s * s)'.

Typo "class Bio()" should be be "class Bio"
