Do not bother paying to go Pro with Memrise. I paid as I am learning both French and German and thought it would be more advanced than the free option. I have reached Level 5 (which I could have for free) however, the Grammar is still on ‘Loop’/Repeat: “Welcome to your first German grammar lesson 
Are you ready?” Seriously the Grammar and Chat lessons DO NOT CHANGE after you go Pro and pay. DO NOT BOTHER it’s a rip-off!!
