taking a year off then doing the exam

Hello,

I’m not sure how much a factor is taking a year off, but least to say i took level 1 in june 2016 (passed and now studying for level 2). I took a year off (didn’t have time in 2017) so here I am now.

Are there a lot of level 1 concepts that are applied to the level 2 exam? I just took a practice exam and a lot of problems were unknown to me (did not see them in the curriculum readings).

Thanks,
