A little trick I use to increase my card memory speed.
If you’re familiar at all with PAO then you know that you have to first translate cards in batches of 3 before you can remember them. Therefore, our memorization speed is limited to our translation speed.
An exercise I do daily is to simply run through the deck and just translate the cards as fast as I can. I don’t care about memorizing them or storing them in a palace…this drill is simply just for translating.
Use a timer and measure you’re progress
I found that after a month of doing this every day for 10-15 minutes, I was able to shave 57 seconds off my total time for memorizing a whole deck (I’m at 1:13 now).
Give it a try!
