Hi Olympia
Only you can answer that question, I have been on a few zoom training courses, whenever you attend a course you have control over what happens such as turning on or off your mic or camera.
All the courses I have been on cameras are usually turned off, once a course starts all mics are turned off to stop feedback and background noise.
If you have Zoom on your ipad then you are halfway there, if you apply to join a meeting and accepted then you will be sent a code to enable you to log in.
I believe if you go on the zoom web site there are some online training. Cannot recommend a Zoom as it depends on your device.
