Why don't other countries use freshman,sophomore,junior,senior??

Was wondering how come no other countries use the terms freshman, sophomore, Junior, and senior?? well I don't know about Canada, but what about UK???

lol Canada does not use Junior shophomore etc. and in Canada a lot of high schools start from grade 10 and go to grade 12, not from grade 9 like you guys do. We also have a entirely different education system and we may be trying to separate our selfs from your educational system

In the UK we have Nursery school which is optional from as young 1 in certain places to 4 or 5. Others only take you from 3 years old. After is primary school from Reception (age 4 or 5) to year 6 (10 turning 11 - 11). Then it's secoundary school which is from year 7 - year 11 (age 11-16) then we have college or sixthform or sixth form college-all the same thing on the same level just a differant environment which starts from age 16 in september after you leave school after your GCSE exams (from mid-May to mid-June) for two-three years depending on your course or whether you passed your GCSE's with A*'s to C's or not. Then you go to Uni from 18-19 if you go through the education system without a break. But you can go to college (NOT SIXTH FORM OR SIXTH FORM COLLEGE WHICH ARE FROM AGE 16-19 ONLY) if you are an adult but you have to pay for it unlike those from 16-19 years old. Everyone has to pay for Uni.

because the rest of the world doesn't come up with BS like so many Americans do!!
We dont use those terms in Australia - simply first, second third fourth etc year student

in ther uk we go up in years. after nursery and reception we have year 1 and 2 in infant school then we have year 3 year 4 year 5 and year 6 in junior school then we have year 7 year 8 year 9 year 10 and year 11 in secondary school. then after that you have a choice of leaving school or going into the sixth form, which is where you do your A-levels.

I don't know but I think it's cool using those names to decipher between the different ages in school years. In australia we just use grade 1- grage 6 in primary school then year 7- year 12 in high school. It's boring doing this and gives no enthusiasm to a student. being called a senior gives you the confidence to do well as you are setting an examply and makes life seem a bit more fun, so I think all countries all over the world should use these terms to differentiate between different student ages.
