I've completed Michel Thomas German Beginners and Advanced course. I completed Duolingo about 50%. I don't know what CEFR level I am currently at. I'm already in Germany, so I'm immersed in the language. I can buy things at shops, ask simple questions etc. in German but cannot have a real conversation.

I have 1 month to self-prepare for Goethe A2 exam.

Since my vocabulary is very weak, I'm using Goethe vocabulary flash cards on Anki. I already know the vocab in A1 list, now I'm learning A2.

I watch slow German videos for listening. I form sentences myself and speak out alone, to practice speaking (people here switch to English because my German is not good enough when I try to have a conversation in German).

I have 3 full-days per week to dedicate to learning German. So, in 1 month: 12 full-days.

Any more pointers? Please tell me it's a realistic goal :)
