Hey. I would really appreciate help from anybody on this! My weaknesses on the mcat are definitely the science sections. B/B and C/P. I feel like I've done so much content review so a lot of my issues...
View ArticleQuick question on Ratios and Proportions
If something is like: A = 3B This means that A is bigger than B, right? As in A is 3 times the mass of B. Whereas if they asked for a ratio, how would that be different? Example: If they asked for the...
View ArticleDrawing fischer projections from wedge dash
Would we have to be able to convert between fischer and wedge/dash? Or would a question just possibly ask in a way where you could just see if the stereocenters match? In BR, they show a diagram going...
