1. ฝึึกหัด - to practice.
2. บางที - maybe, perhaps. (This word, in some contexts, apparently also means 'sometimes')
I spent a few hours yesterday with Thai, writing charts and practice sentences and making little notes on grammar bits and such. The best thing I got to doing yesterday was to listen to example sentences and write them down as I listened, and then check my spelling afterward. Most were vocabulary words I've already 'learned' or at least know how to say and recognize, but spelling is kind of hard. So that was great practice.
