Study in Spanish

We bought a Sandwich and were looking for a taxi, but the streets were so crowded that we had to wait nearly one hour to find a cab. We even had to walk a few blocks in order to catch one.
I have studied at the faculty of Engineering. Just tell me about your difficulties and I'll try to help you. I would really like to help you with learning English. Kind regards and speak to you soon.
We first took a regular bus to the border, which was basically just an empty building. There we switched to Jeeps, as the terrain was rocky. In our group there were 4 American girls and us.
