After Fundamentals before Foundation

I'm half way through Fundamentals and got hit with a lawyer bill which is going to delay my Foundation purchase. What would be the best routine to keep the momentum going until I purchase Foundation?

I plan to go back through Fundamentals and note the things that I have the most trouble with (probably should've been doing that already) and work on them while still practicing the rest. Just wondered if there was a more structured plan to follow.

Thanks.

At this stage there is not a more structured interim plan. 

More fundamentals is certainly not going to hurt you; you may wish to start a thread about the elements you find most difficult and start a discussionon gettinf started opening these areas up
