some students really didnt go to sch la, cos they are so faraway
from the campus...miles and miles away in fact...
the going to the TA office hour is optional one, if u r very smart
and know how to solve all the assignment questions, then dun need
to go...or can just get help from the TA online, but she is only
reserved to help those who are not living on campus...
so me not smart and living on campus, hence need to spend extra
time going to office hour lor
