Yes, this is how a student spends five minutes to 10 minutes, 10 minutes to an hour, an hour to the whole day on social media with their mobile phones. As a result, they waste important time in their career formation, due to which a student does not get enough time to prepare before the exam. If you don't prepare well for the exam, you won't get good results, and if you don't get good results, it will have a huge impact on your career.
They're still students and they have nothing to worry about and that's why. If they have lived a poor life, they won't waste time but spending a couple of minutes per day into these socials, that's fine. We're all entitled to get entertained with our phones and whatever we browse in there. But compromising such as exams for that and wasting time, it's their choice and they are irresponsible if it affects their studies.
A student will use a phone but it must be limited and he must use the phone for entertainment. As guardians, parents should definitely monitor how their children are using the phone. Nowadays, parents are not very aware of their children's phone usage, which is why children usually use their phones to engage in antisocial activities and do whatever it takes to ruin their careers. However, if a student uses the phone for an hour every day, it will not cause any problem, but if a student uses the phone for more than 10 hours in 24 hours, it can be guaranteed that their career will definitely be ruined.
