In the first or introductory lecture of a course, either associate professors or professors of my university tells to students to clarify doubts with teaching assistants. Faculty do not say to students any explicit statements regarding how, when and where to ask doubts.
In general no course site or any centralized communication channel is present.
Most of the students comes with lot of doubts without proper study and asks for TA time individually. For example some students asks TA to tell the entire course in an easy manner. Some students asks advance questions that TA cannot answer. Some students ask for mobile number, personal mail etc., Some students asks for appointment and lot of time for discussions.
In the scenario of academics, is it apt for a TA to inform to the corresponding faculty about these issues or is it apt to give strict instructions to students in the absence of the faculty regarding how to ask, where to ask and when to ask their doubts based on TA's personal comfort?
Note: I am asking this because faculty consider these as minor issues. But as a TA, one mayn't able to manage such unorganized stuff.
