Hilchos Brachos:
1. When you make a bracha rishona, which foods are covered by your bracha? This comes up every day, and if someone hasn’t learned hilchos brachos (which many people have not), they should have this sheilah every day.
Also, even if you have learned it in depth, you should still have a particular sheilah because there is a crucial aspect that is not clear, and it is possible to understand the relevant sources in two different ways, and it’s understood differently by two different authors of Hilchos Brachos sefarim. (which is why I called up each of them and asked them to explain their reasoning before I taught those halachos).
2. Shinui Makom questions. This can involve many situations and many questions, which you would have if you haven’t learned the halachos.
Also, even after learning the halachos, there was at least one question that I still had, and apparently, it’s not clear, because I asked two different Rabbanim and got two different answers.
The question is: If you are eating potato chips (for example), and you leave the house but plan to continue eating the potato chips in your new location, should you make a bracha achrona first? (according to the one who said you make a b”a, you would have to wait before resuming eating – I forgot how long, I think it was app. 20 minutes, but it could have been 30 or 15, and according to the other one, you should not wait too long).
