Lack of improvement

I have had a lack of improvement recently I got through maybe 230 sentences this week. Thats like 2.5 days worth of work. but it took me 8. I'm busy blah blah blah not really an excuse. Getting through KO2001 shot up to be like 3 times as fast Kanji->kana so i will stick with it. Kore are easy and can run through 50+ in an hour taking breaks. and Kore reviews take like 5 per minute. Seriously easy work. or maybe thats just the beginning of the Kore sentences? I doubt it its just pretty easy work. I added some more sentences from my textbook and All about particles. But Japanese is taking a back burner for the next two weeks so i can prepare for :

Calc 5 final ( Probably a fail ),
DMC Final and Design Project (shooting for B status),
Japanese Oral Presentation and Oral exam Japanese Final Japanese test and quizzes etc ( going for B+ in the class, didn't do hw cuz i was doing RTK lol ),
Engineering Economics ( Gimme an A or at least a B+)
Properties of Materials ( Be happy with a C )

Lots of Non Japanese Reading in my immediate future.
Lots of studying needs to get done and Japanese will just have to wait.

I'll probably still add some but not really stressing it.
