text: it may be harder to understand because demonstrations may be a little unclear through a video. when there is a need for a question, doing classes online there's no one to ask at times so students have to go the extra mile of looking into researches, YouTube videos, etc before they're able to understand. something which waste time from their studies and brings conflict. Video conferencing is not advisable and taking classes may be better face to face which brings peace and makes things better.
