How can I persuade my parents to buy a laptop? They think that the laptop would distract me from school. But I think he would even help me learn.
Probably not at all, no one believes the fairy tales of "I use it to learn and do my homework" anyway.
He won't help you a bit at school. Or just a little. But is a good argument. It also worked for me.
They think that the laptop would distract me from school.
You already mentioned the main argument…
-he would even help with learning
-it skills in today's professional life are indispensable ---> important for your later life
- agree rules e.g. "Not after 9:00 pm" or "You can move it in at any time if I don't behave"
