When learning Riichi Mahjong whats the easiest way you've found to memorize the yaku?

I want to increase the available options for a win condition as a new player. I've found a flash card site like this one

While boring it does the trick but isn't as fun as just playing. In the meantime I've resolved myself to playing tenhou and against AI on my phone while just memorizing the most common yaku like Menzen tsumo, Riichi, Tanyao, Iipeikou, Yakuhai (seems like the easiest open hand to use). And relying on the Automatic scoring of the various software. I have purchased a Mahjong set and plan on playing IRL games so I want to get good enough to memorize all the Yaku and do my own scoring like you see in the anime's and shows how they're about to announce how many points are due immediately upon declaring Tsumo, or Ron.
