I still remember reading like the entire zabuza arc in shounen jump when it was being printed in english but before it was ALL printed in english despite having only done that like
yeah, my memories of Naruto are early-early stuff (which I liked, other than Naruto getting a little creepery on Sakura at times), zabuza, the chunin exams, sasuke retrieval, finding tsunade, ???, slapfight on the roof, sasuke runs away, timeskip, ???, uchiha drama, pain, uchiha drama, ???, sasuke stuff, samurai, ninja war, sudden ninja space goddess.
I was under the impression Sakura was the only one who could actually answer the test other than the plants or else I feel like it would be treated as more notable
To me, the mirror setup doesn't look like something she could use for herself, as opposed to helping out Lee, at least not without being obvious enough to get pinged about it, but that's just my read on this.
That said, my take on it is more that Sakura knew all of the answers, but Tenten and Hinata probably knew enough to pass. Like, the first question is a difficult code. The second is just a math question. The third's about tactics. The fourth is complex chemistry that can't actually be solved, so probably a trick question. The fifth is unknown.
I never watched the anime but caught one episode by chance which was during the exams where they were all using their Ninja abilities to cheat and that was one of the funniest and best things i've seen in anime. (I ended up reading the entire manga a few years after it ended and I think overall it was pretty good?)
