7% AER on 3600gbp/ year worth it? What other options are out there?

I am relativley new to investing. A bank is offering 7%AER on 3600gbp for 1 year. Gain according to the banks website is around 136gbp.

This sounds like a not very good return but it is safe. What other options are out there? ETFs?

Background:

Currently studying Computer Science at University and may need the money 2-3 years down the line.

Thank you!
