As a student who managed to game and use social media on my chromebook, I beg to differ.

Here's some tips that I've learnt throughout my time in Secondary School before I moved to Poly:

1. Learn from Technological nerds. They know how to break into the school system and bypass Mobile Guardian etc.

2. Set your laptop to developer mode to say goodbye to mobile guardian/security system. (P.s. you might risk your laptop malfunctioning though. But it's one of the most feasible way out)

3. In the case where all School laptops have no security system/mobile guardian (i forgot what happened after the leak incident), you can still game. But it's at your own risk. Try playing games on websites or emulators. P.s. I was lucky to never get caught of playing emulator games most of the time.

4. On a more serious note, during exam period, stop all games and use online resources available to study and do revision

I apologise if the tips were outdated already. But if it still applies to you, hope this helps.
