For option 1: Do you think your scholarship can cover other cost such as accomodation and food? Is it only a tuition fee scholarship? If it is then it is going to be quite stressful to work and study at the same time. How is your family finances? Are they able to subsidize some additional cost should it be incurred on your side? But are u going on scholarship to get a masters or degree?

Option 2: 80% increase? That seems pretty high. I would look at current family financial situation first and make an honest assestment. While most parents will say that all is fine, it would help if you do your own investigation and see if it is really fine.

For me it all boils down to money. If you have enough savings and ur family can tahan a bit then go for (1). If not go for (2).
