My name is Arturo, I'm a laws student. I like to drive and to travel. I love to get to know places (This sounds a bit awkward, "I like to visit new places might be better."), I like the music and the reading. I could practiced cycling when I was a boy. I will learn english.

Nice Job, Arturo! If you are writing a statement that contains a complete thought it is better to use a period. You could use a comma to link similar thoughts such as:

"I like to drive, travel, and read."

"I could practice cycling," infers that you were able to practice cycling when you were a boy but you are no longer able to practice cycling. "I practiced cycling," suggested that you used to practice cycling but no longer do that.

Goodwork!
