In my solo campaign I played the "Home teacher" (The card that shows Obi Wan) and chose that as my first fixed profession for the following rounds. The card says something like:
At the end of the game you receive one bonus point for every profession you play after this one.
1 In the second game when I already have the teacher laying on the table and choose profession. Is that profession free or does it cost 1 food?
2 Also from the third game on I had the Teacher and other professions laying on the table from the start. Do all these professions give bonus points at the end or just the ones I actually play in that round?
