I have 10 more of the Duke lessons left, which I would like to finish in about a month. The total set of 25 is supposed to equal about 1 semester's worth of study.
The general per week goals are:
2-4 Lessons completed for Grammar
1 movie or several dialogs from the Asher book for Listening Skills
The third week of February I have some additional work deadlines, so I may be modifying Tamil learning goals for that week down to some review of previous lessons as opposed to doing anything new.
