Answer:
Somtimes, students are embarresed to ask their teacher either face to face or online. One solution students can use is to privately message him/her. It is because teachers can pay more attention to you and try to make you understand about the topic youre learning. You can also make a video call and ask them about the things you dont understand. Dont forget your manners and always ask for permission before calling them. Wear an appropriate outfit and keep the converaation going.
I am so sorry if there is a typo or I spelled it incorrectly.
