Suggested kata and progression

[ClipClopBoom]

Picked this up recently; I'm an aero engineer but find myself having to write code more and more.

It only gives me options for fundamentals or rank up; do options change as I progress through ranks or is it always like this?

Got a good handle on data structures now but I'm wondering if there's a way to focus on algorithms etc. without having to trawl the complete list every time I want to try a kata.

Thanks.
