Today's class (Raúl García)

I started my day with AWS class, we had to make diferent virtual machines on amazon web services, so we could put a web page, on which you had to register to see it. I wasn't sure about how to make the "EC2 instances" so I had to watch a YouTube video, I didn't had enought time, but next week we will have more time. Next we had english class, we started with an exam, for me it was easy, so I didn't had any problem there.

I will make the project with Samuel, he is one of my best friends here in puenteuropa, we will do great for sure!
