Going to two different decks every day kinda sucked.. not only because one would be done in 10 minutes and the other drag on forever but also because I couldn't show my progress easily. So I combined my two decks (Step 1 and Step 2) into a new deck.. I think I have a trick for adding in new decks so I don't loose my progress now. Each time I finish my current deck, I add (download and then import) my new deck (the next step). We'll see if it works in a week or two I guess :)
I found that once I mixed the two decks it was a lot more fun as there were some that I already knew from the old deck. Made me feel like I was making better progress too.
