Learn bit by bit as you receive material, it makes it way easier and the work load is smaller! Personally when learning Irish I constantly repeat line by line :) For orals, you can record an audio of you saying the piece and listen to it! I find that helpful for sraith pictiúirs!
usually for essays i try to write the paragraphs on different flashcards and that usually helps me learn them. i also find it easier to write down how many sentences i have in each paragraph which i find helps me remeber. hope that helps :)
