How to maximize a free time at work?

Hi, everyone!

I really like studying computer science. I try to learn whenever I have free time. But here’s the thing—I work at a hotel front desk, and I often have time when no one is using the computer. The problem is, people interrupt me a lot. So, I only get short 5-10 minute breaks every 30 minutes to do my work. It’s tough to learn because of these interruptions; I can’t concentrate well.

Any suggestions to make learning easier in this situation?
