I second that, aeh. I'm pretty sure that if I do a lot of spare reading in my time, then I will build a lot of vocabulary. The only problem is, I have barely any patience for complex text.

Context within what I am reading matters. For example, on the post-2015 SAT the vocabulary-in-context questions are the easiest for me, since their implications are easy to understand. However, on a pre-2015 SAT, sentence completion and analogies tend to be difficult to because of how complex the words are. There is definitely quite a bit to learn in the world!
