Do you think it would be too hard for me to work part time and go to school full time?
It sounds like a lot of work, do you need to go to school full time?
I want to complete my degree faster.
It will take hard work and focus, but I think you can do it. Manage your time well and stay focused and you should do well.
I hope I can make it work, but I'm worried about the stress and workload.
Completing your degree will help you to find the right career for your future.  Stay positive and motivated and you'll do very well with your studies and earn enough money from your part-time job to support yourself.
