The amount of verbs has gone somewhat out of proportion in the last two lessons, hasn't it?... But that's for a reason! First of all, now we are dealing with the biggest verb group out there. And the second reason is that the verbs are at the heart of any language, and for Hebrew, a root-based Semitic language, even more so.
To help you manage the collection that may have started being confusing, in addition to the Blackboard Flipping Stickers Game I made an additional Memrise deck for you - targeted solely at present/infinitive verb review! See the link below :)
Besides, I hope you remember to back up your growing vocabulary with words from random sources - and if you haven't started doing it - now is high time to do so! Curiosity is crucial for language-learning. :)
