Being a student, after I study a topic and google its collaterals, I felt this is the community where I can ask any entry level question whether to get guidance or specific questions, whether it is homework, post test, research or for the sake of getting a deeper understanding. However, it seems that this community deliberately underestimate such questions. The answers are usually with a sarcastic tone, worse is questions are simply closed for no reasons do not cover the students' scope! If this community cannot tolerate students, I suggest excluding this entity from the community description, if it is related to the guidelines, I suggest to change guidelines to suite students scopes. However; keeping shutting down students won't help the q&a purpose that this community established upon. I hope that my voice find its echo to improve this community.
I feel I can kinda answer this question. I was a high school student not too long ago and asked dozens of well received questions exclusively related to high school Chemistry. I even got the Inquisitive badge, but before I got to Socratic badge I left high school :(
To start with, this community is not built with any particular community (like high school students) in mind. Questions are solely voted upon based on their quality. To a very large degree, it does not matter if you're a high school student or a professional chemist or even a non-chemist. If you have a question in mind, you can post it here.
Anyway, I can understand your frustration, and it's common to new users. I looked at your four questions posted so far and they are ... okay. There's at least a couple of red flags: 1. bad quality image posted via phone 2. discussing multiple questions in the same single post. Even the question on diol with alkene, to me and you it seems a straightforward question with an undisputed answer, but the professional chemists would know that its probably a lot more complicated, which is why it got close voted.
I understand that these questions could be edited by a veteran here to make them better, and I used to do such edits when I was active, but not everyone has enough free time to do edits or teach the newcomers step-by-step what the rules are. Understanding a new question and posting an answer to it is already quite involving, so any more than that is asking for a lot more of free volunteer time.
Most confusion for newcomers arises because this site is a Q&A site, not a forum. The questions here are generally specific, and they are to build a reservoir of quality question-answer pool, not to have a discussion. A general rule of thumb is that if you want to have discussion around ideas or "to get guidance" (as you said), it's best to not post here, but on other Chemistry forums. However, if you have a concrete question in mind, you can surely post here and get it answered.
It's not to say that the system is perfect, as sometimes good stuff gets close voted too, but overall this is a system that all StackExchange sites are born with, and it's how it works. Many people do get their questions answered here, so if you just wander around here for some time, you'll get the hang of what kind of content generally gets a positive reception, and then you can start posting in the same spirit too. Good luck!
