On math.SE, a “question and answer site for people studying math at any level and professionals in related fields”, it's no problem to post your own solution of a problem and ask if it is correct.
On physics.SE, described as a site for “researchers, academics and students of physics” similar questions have a good chance to be closed. It is assumed that you should rather ask your fellow students. It's not for a site for somebody informally (outside of an institution) studying physics.
Philosophy.SE doesn't exclude such users, but if you ask here if your own argument or interpretation is correct, you will run into trouble, too. The close reason is, as we all know:
"Questions that push a personal philosophy with no question beyond "am I right" or "what do you think" are off-topic here as this is not a blog. It's ok to express unique opinions, but you must have an actual, answerable question to go with them."
But users posting a problem in formal logic including their own solution and asking ”am I right?” don't get their questions closed. In this regard we're similar to math.SE.
If such questions are okay here, then how much is a question, if one's argument, solution or interpretation is correct, allowed to be thematically different from a formal logic question?
Of course, formal logic questions are the most definitely answerable questions on this site. But there might be “Am I right?”-questions which are similarly definitely answerable. If somebody asked “I've read Kant and it seems to me he is a consequentialist, because [a)... b) ... c)...] . Am I right?” a definite answer could be “No! You've clearly interpreted him wrong: [Explaining serious misunderstandings of a) ... b) ... c)] ...”
