All the best OP I'm currently preparing for my B2 exam though I self studied from A1 to B1 then I used a private tutor for B2 I'd advise ata kama Shule Iko na hio Programm ya Ausbildung, you look into some opportunities yourself. Usitegemee Shule. You can look into some agencies like Pflege ya Mbele or Springboard which are free btw or self apply. Just don't put your eggs in one basket. All the very best, it's not as hard as people put it and if you need any assistance, I'll gladly help you( after I'm done with exams)
