During my class today we were studying N1 Grammar といい. In our textbook there was the question:
a) スポーツはみな楽しい b) 私はお子様に習わせている c) 私はやったことがない
So I understand that a) is a correct answer, but I had trouble with c). The teacher explained to me that the grammar point is supposed to be used with the speaker's evaluation of the topic (評価) along side an adjective. They mentioned that because c) is related to the speaker's experience (経験) instead of (評価), the grammar cannot be used. I believe they were thinking I was aiming for a sentence like (水泳もテニスも私はやったことがない).
My argument actually was that the answer wasn't mutually exclusive to only one, since my thinking that lead to C) was that because the speaker hadn't tried those two activities before, it may seem to them as fun to try (as an evaluation after hearing them). The teacher was surprised, but didn't really give me a clear answer of whether or not being that case would still remain incorrect, (replied with あ、そんな考え方もあるんですね！) and moved on to make sure I understood why a) was correct.
