Don’t want this to come off as advertising or endorsing another website, but over at Nihonshock, they’ve made another 8 cheat sheets and redesigned the first free one.
These look extremely tempting to buy and the price is decent too. $25 USD for the lot. S+H is free if you’re in NA or $7 for the rest of the world. Lloyd Vincent (the guy who made them), lived and worked in Japan for 5 years as a translator and passed level 1 of the JLPT. The info contained in these is going to be of a reliable high standard.
Yeah a digital version is in the works but I suspect he’s concerned that people will just upload them to different sites and share amongst each other, and won’t really make a profit on them. He must of put a lot of time and money into these so for now the safest way is to only provide the physical copies of them.
The original free cheat sheet is still available to download in digital format though.
