Sorry for the misunderstanding. The height increase you are refering to is caused by crouch-jumping and strafing. In level two particularly try jumping from the right side of the enemy while holding A+W and slowly move your mouse so that you'll reach the left side of the wall at the peak of your jump. Its important to not be crouching and to be facing almost sideways when you hit the wall. Also make sure you are not messing up the crouch-jump order (It's jump first then crouch), sounds silly but i've made that mistake many times before. Hope this helps.

You have to use GDJ, check out janik's vid on the guides tab
