Strong A2 for sure, especially the more you know the Fluenz materials. But even mastering them you would likely still be A2.

That said, the big step-up into the B1 range would just come down to vocabulary. If you do any additional learning, listening, reading, talking outside of Fluenz and using new vocabulary from time to time you will be in the B1 for sure.

There are probably around 1,500 individual words in all 5 levels with multiple combinations of words so you get practice via some repetition but if we go with 1,500 words or so, you need more to really be solidly in B level range.

You can pick-up vocabulary pretty quickly, especially if you read subjects that you are interested in as well as listening to radio or TV shows that interest you as well.

I would guess that if you only did Fluenz and maximized your learning from it that you could pick-up enough additional vocabulary to be a B1 within a couple of months at most. You will also be able to learn new words faster as you will already have a good base from fluenz.

Fluenz rocks and is probably the best program for building a strong base to grow from for sure.

I combine it and dreamingspanish (free youtube channel or $8 for the website which has more stuff) as well as different readers from complete novice to intermediate. The books I use mostly are from CPLI (command performance books). Each book is made up of around 400 different words total. Reading the book exposes you to the same words in different ways multiple times. By the time you go through each book a couple of times you really can add vocabulary to your brain.

Good luck!

I don't mean to ask the obvious but....have you checked your microphone settings on your Mac? Maybe it is set very low. Alternatively - are there other softwares that you can record you speaking into the same microphone and then seeing the sound level that it plays back at? This way you can see if it is consistent across different programs. If it is, then it would point to either your microphone settings or your microphone. If you do use things like Zoom with your microphone you do need to be aware that some things will have custom settings within them that override what the computer is set at, but those settings only apply to that program. What I mean here is that if you have no issue in another program, that might have the microphone input jacked up from what your computer is set at. I am putting in a "source" so there should be a link to Apple's web page that tells you how to change the microphone setting so you can test if that is the issue.
