8 Classes Left for BS - Started 1 Month Ago

I have these 8 classes (27 competency units) left, after finishing 19 classes (57 competency units). I started June of this year, so officially past the one month mark. I am feeling the exhaustion in my mind now lol. Struggling through Intro to IT--any suggestions? As for these other courses, any tips or suggestions? I am nervous for Quantitative Analysis and Business Simulation.
