I'm crawling like a snail on First Greek Book, too. It's Lesson 16 that just I got to. The man White explains everything in quite a different manner than Chase and Philipps do, which is refreshing.
Keesa, have a quick glance over everything first, then read them all carefully once more. Since it's not a couple of day's job, if you are doing it in once in a bluemoon way, previous learnings would slip away from your memory. Quick survey of what you plan to attack, repeatedly once a while, will help your memory. And your learning will be like a review of what you once met.
