@HunterThoss made the same mistake. I thought we weren't supposed to assume that.....

I am in the exact same situation and am also a full time student that works daily. I personally have held off on doing practice questions until I am done atleast with the majority of the LR lessons - as I feel that it would be a waste of the limited question pool to do questions now when I am not adaquetely prepared for them yet. The practice questions scattered throughout the lessons are very helpful for me.
