I found WSET2 exam questions flesh cards here and actually it's really amazing because it's so difficult to find such topic on other apps.

Easy to use, pleasant interface, user friendly

Brainscape uses the proven technique of using flash cards to study/enhance retention of your subject. I used their pro version to prepare for my WSET Level 3 in Spirits exam and I am confident that I succeeded in the tests (no results yet as of this review). Brainscape also made me more disciplined in my studies with the metrics built into the app so that I can easily see topics that I was weak in and devote more time to. All in all, I truly recommend this app for anyone taking up a certification exam. 2 thumbs up!
