how did u go 點解?

a:I got good results in tests
b: how did you go

你怎樣取得好成績.
因為 a 話 自己拎到好成績.

或者.
a : i've just finished my test
b: how did you go

即係你考成點

b's response doesnt make any sense.
it should be something like: how did you achieve that? or how did you do that?

　你怎么去

how did you go

I guess your sentence is similiar to "how can you do that"
你怎樣可以做到

你如何取得這麼好的成績?

怎麼您去
