thank you meera dahling. at least you got my Question correct.
I thought NepaliUS students were not getting my question or did not understand at all due
to their lack of English language. I mean don't get me wrong but US do speak and write English but
it's not up to world standard. I have met Japanese/Chinese/Russia/Indian tourists who can speak and
write better English than Americans.

Example:

British English           American English
centre                       center
theatre                      theater
realise                       realize
catalogue                  catalog
programme               program
travelled                    traveled
neighbour                  neighbor
grey                          gray
plough                       plow
practise                     practice
cheque                      check
tea                            coffee
left                            right
right                          left
refrigerator                freezer
cafeteria                    coffeehouse   
taxi                           cab
lift                             elevator
1st floor                    ground floor
train                          subway
football                     soccer
rugby                        football
cricket                      baseball
hockey                     ice-hockey
car                           automobile
handphone               cell
loo/toilet                  bathroom
bath                         shower

Now do you believe me why US education only works in USA!!

An institute not teaching standard english and a nation who deviates from speaking and writing proper
english cannot be smart.
