If you start learning Mishnayos Megillah on the fourth day of Adar (Shabbos, March 4th) and learn just three Mishnayos a day (after Maariv, with your son, etc.), you will complete the entire mesechta on Purim, and if you then continue to learn Mishnayos Pesachim starting on Purim (it is a mitzvah to begin learning Hilchos Pesach on Purim, as brought in the Shulchan Aruch, Orach Chayim 429; Mishne Berurah seif katan 2), you will complete the entire Mishnayos Pesachim before Pesach!
