Memory works best structured. Knowing that there were two US VPs who served as such for different presidents gets you a few hundred points on Jeopardy, but is otherwise kind of pointless; knowing how this happened tells you something about the early Republic, with whose consequences we live today. So go beyond the "facts" to what they summarize. Grammar is never going to thrill most of us. But you should for your own sake learn some foreign languages, and in many of those it is damned handy to know an accusative from a dative or an infinitive from a participle. Again, learn with the use.
