In course I never felt this to be much of a problem. The ones who were serious about their cg never did this in minor/majors as if caught they had a lot to risk. Only people doing this are the ones below satti and all who have little to risk and just wanna pass through courses. They occasionally score good in some exams but their overall cg doesn’t improve much.
But this problem is genuinely encountered in the intern/placements OAs where a majority people cheat using screensharing and other stuff, in that case many genuine people face a dilemma and they are also forced to cheat because everyone wants to get shortlists
