A person wants to be proficient in halacha.
1) Should he learn halachos: a) that pertain to his fellow man? - I.e. Shemiras HaLoshon, Stealing or Ribis etc. b) or to his Creator? (I.e. Shabbos, Berachos or Milk and meat)
2) Is there a specific order of which category of halacha he should learn first?
3) How many times should he review that category of halacha, before he goes onto a new topic?
