小学与中学同学的英文的简称

不论中学还是小学，同学有两种：
同班同学 classmate
小学同学 primary school classmate; elementary school classmate

同样同学（校友）schoolmate
中学同学：middle school classmate; grade school classmate

以上如果指同样的，非同班，则用schoolmate

补充：不是什么东西都有“简称”的

The junior classmates is the first classmates of our studying life .the friendship between the junior is always innocence !
The middle school classmates is a good partner of our studying process !The teamwork make us understand the importance of friend and the friendship is more stronger than junior friendship !

小学P.
中学S.

同学，classmate

不知道还有这个区别，学习了
