Hiya, I was studying these words and I've read on internet that, for example 小学and 小学校, which mean elementary school, are not used in the same contexts. That is, they mean the same, but its usege is different, they are not interchangeable. Could anyone explain me when is 小学校 instead of 小学?
And the same thing happens with 中学 and 中学校.
Thank you in advance.
