UWSA2 Scored 560 (232)

I just took UWSA2, started with 71%, 76% an then bombed it with 67%, and 54% (yeek, what happend in this block I don't know) may be I took it late 3 AM and I was hypoglycemic so that might be a reason but no excuse, final it was 232 (560)
exam is in 2nd week of March, those who has already taken this beast please suggest me how should I proceed from here,
I am aiming for 230 plus.
any input will be highly appreciated!
