Free online Cambridge B2 practice exam

Hello! I'm looking for 2 or 3 students to try out my online Cambridge B2 practice exam.
 This will be the full 2022 exam; Reading and use of English, Listening, Writing and Speaking.
 I'm offering this for free so I can test the online forms. The speaking exam will be done over whatsapp or Google meet. 
 The only thing I ask for in return is some general feedback about the exam,ease of use, loading times, appearence etc. 
 So, if you or someone you know is interested in doing a full practice exam please get in touch via the email address.
