遘問呢篇英文打成點呢?文法正確嗎?

Today Brian drove me to City East Campus. I should have a lecture at 11am. It was 11:05 am already and so was a bit late. I got to the campus and found no Level 1 in the C Building. Where is room CB1-01?

Finally I went to the reception of SAIBT and B Building with Kavitha, a classmate in Dip IT who is from Sri Lanka. The reception called somebody for help and the answer was terrible.

Today, Brian drove me to the City East Campus. I had a lecture at 11am, but I arrived a bit late at 11:05am. I searched around and around for room CB1-01. I walked through the entire C building, and it has no level 1. Finally I arrived at the reception of SAIBT in the B building and found Kavitha, a friend from Sri Lanka who works at Dip IT. He (or she?) called someone else and got a terrible answer.

(XXX In addition, did you meet Kavitha in building B, or had you been running around with him/her?)
