実践 and 実戦 in exercises


I've seen both 実践 and 実戦 used in the context of practice questions, both
pronounced じっせん, of course.

実践問題 seems to be the more common of the two, meaning a practice exercise, but
I've recently come across one which instead says 実戦問題.

Firstly, I'd like to confirm this isn't a typo, given that 実戦 refers to
combat. If the text is correct, and both 実戦問題 and 実践問題 are technically
accepted, Is there a difference in meaning or nuance between the two?




In Japan, entrance exams (usually of college; sometimes of high school and
middle school) are often compared to battle or war. For example, the slogan of
代々木{よよぎ}ゼミナール, one of the largest entrance exam prep school, is
日々是決戦{ひびこれけっせん} (decisive battle every day). So 実戦問題 is a kind of pun and
means super-practical, must-learn problems.
