This is a short-term training for emergency technism, and people who finish the 50 hours of lecture and pass a series of exams can have a license and have some ability to help people in need.

Actually some lectures are boring because they are too simple for me and always Iet me doze off. However, there are still fun sometimes.

Like today, we met a interested doctor. He was a urologist and taught us about urologica trauma and related diseases we might deal with. Because he took the wrong message so he thought we are doctors who recceiving re-education. Therefore he prepared very professional lecture for us. All his powerpoint were presented in English, most of my classmates nearly could't understand the content, but I was high because that was very chanllenging and at least I could understand most content in the slides,and I could write them all down in short times. The doctor was also specail, too. Although he knew that we are idiots in his field, he didn't stop asking questions like the Dr. House in drama. I was happy at that time because I got a right answer in one question! I really liked the doctor and this was my favorite class so far.

The course is going to the end, and I hope that I can pass that in high grades!
