Hint 1 . Before starting the meeting, you can open this document and work on it. When the meeting starts, this document will be sent to your student.
Hint 2 . You can create a lesson using TalkAndWrite and send it by email to your student. He/she can work alone, as if doing a homework. When you start the meeting, all work done offline will be seen by both of you.
Hint 3. Since you are using the PRO version, you can have unlimited session time, even if he/she has the BASIC version.
Hint 4 . For large files, it will be faster if you open the document, save it as TalkAndWrite background (File => Save Background) and send it to your student by file transfer or email before starting the meeting.
