The app is not convenient to use. Specifically when you do questions, it loose your progress just by self resetting, it allows to push continue by mistake without making choice, it does not fit to the screen that makes you scrolling back and forward and sometimes as a result it resets and you need to start again the questions...

i cant open this app in my phone. Honestly, it's a better portal compared to others, but I can do it with my cell phone when I'm free or when I want to learn.
