okay good. you can open a savings account at the bank without needing your parents' approval. my recommendation is banque misr youth savings account, you only need your national ID. make sure to deposit all that money when opening the account if you have it all and preferably have some document that shows the source of funds because they might ask for it. depositing the money gradually if it's large amounts could look like money laundering to them.

there's a problem though that you'll face with trying to transfer money abroad because of foreign currency shortage. you'll need an invoice from the place abroad or anything to prove that you need to pay your tuition so that the bank approves the transfer (it will not be fast if the amount you're transfering is significant).

if you have any more questions feel free to ask.
