Maycee, I just finished my first semester in the BSN program and I used 3 ring, 1 inch binders. For some classes, with the big syllabi, I used 1 1/2 inch binders. To help with organization I used one binder/class instead of combining everything because you're about to learn alot. Also I used individual notebooks..i think thats what they're called (college rule) just in case you have extra notes to write that won't fit on the slides. For pharmacology, I had two notebooks, one for the already learned material and one for the new material that we had not tested over yet. And the subject dividers are good as well. Good Luck with your first semester, it won't be easy but take it one step at a time.
