If I had to choose, I'd probably go for the 5.00 CGPA. Education seems like the safer bet for long-term success.
Depending on the rule of the game, if not one can still risk school go for the 5btc and when you have meet up all the requirements to get those 5btc you can always go back to school study and get those good grade you deserve as the fund from the BTC can really go a long way in serving you in your educational career. Don’t forget you need money in other to complete those tasks, test book tuition fee and everything about school requires you to pay for them which is where the 5btc funds comes in.
