First, thanks to the organizers for this amazing site. This is becoming indispensable resource for me, as I'm learning Hebrew using the FSI Hebrew Basic course. I'm currently on unit 1.1, however

My question is how long should I spend on each Basic Conversation? I have spent around 2 hours reading and rereading and listening. I still can't say the whole thing without pause from memory. Should I keep going with the Basic Convo or should I move on to the next? What is the general timeframe for one of them? How about a whole unit?
Thanks,
Sam
