The ZOOM meetings are started by the tutors, a link to be sent to the email address provided on the request for tutor form. You will click the link at the start time of your appointment and your tutoring will begin.
Use your school email to sign-in to the zoom account, it is free.
If you are having trouble being heard/hearing others in the meeting, check that you are using the correct microphone/speaker and try headphones if available.
Use the chat feature if the area you are in is loud or if you are having trouble hearing/being heard.
Connection troubles can cause screen share to not work/stop working; make sure you have a good connection and connect without video if necessary.
If you are experiencing problems with the zoom session, try leaving and reconnecting with the link sent to you, that can solve many technical problems you may experience.
