Free online practice Cambridge B2 (first) exam

Hello!
I am offering 2 or 3 students the opportunity to do my online Cambridge B2 exam for free. I am in the late stages of development and would like some feedback on ease of use, appearence etc.
The is an online version of the 2022 cambridge B2 exams. The reading and use of language, listening and writing exams can all be done whenever you like. We will need to arrange a time to do the speaking exam via Whatsapp, Google Meet etc.

If you or somebody you know is interested send me a maessage I can discuss the details further.

Many thanks,

Henry Walker
