Hi,

I had A1 as well before and got grade of 7 out of 9. And I'll take the Speaking and listening test (B1) on May. I think even you wife has A1 and first class she still has to take the B1 because B1 is a lot higher than A1.

A1 is just the basic user for Common European Framework of Reference (CEFR) after A1 there's A2 then B1, B2, C1 and C2.. Half of A2 to C1 categorise as independent user and C2 is proficient user.

That's why I think even we had A1 before we still have to take this B1.

Regards
