We use our own smartphones as part of studying since the start of (equivalent to) high school. Teachers send us notes electronically, we read them there. Sometimes teachers may ask us to search something because they only have old feature phones and most of us have data. We even do tests on them via EduPage, although that one may not be the best idea due to the ease of cheating.

Sure, we do have computers at school, but the network is often broken, and many of them still run Windows XP. And those that got upgraded to Windows 10 have many issues because the hardware can't handle it.
