Not to brag or anything but I learned pretty fast and this didn't feel hard for me. But I think it's because you're not doing it the easiest way imo which is the daequan way. basically using turbo build (or maybe not) you do a circle again and again, when you go up you build ramps, then when doing the bottom part of the circle you place your walls, also you actually place your ramp right after your walls and not the opposite. When you're near the edge of the ramp that is. So it goes like this :

Double ramp - little pause - double walls (downer part)- double ramp (upper part) as you're nearing the edge

If you're in turbo mode just hold mouse button and stay in stairs until you're at the edge and then switch to walls and back to stairs
