They'll get harder (A lot harder) the important thing to remember is (and Iv'e been a victim of this, ask Domuk or SAJ) even if a challenge looks impossible (and some do), and you begin to sit back and think, "No, this is above me, i simply can't do it" you need to ignore that thought and replace it with "I can do this, I'm just missing something, lets look at it from a different angle, or maybe start completely from scratch", because you'll learn about it, and eventually you'll pass it, thus increasing your skillset :)
