> At some point, you need people to check your work, though, Agree with that, 100%. Most of my students will, at some point in a course, respond to questions with things that are completely wrong. It's just how people learn. If there was not someone to correct their mistake then they would struggle a lot to find the error and fix it. One of the most rewarding things about working with students is helping them through tough spots. But it is real work, and takes the time and attention of someone who has training. > but you can search for online communities to do that. E.g. a post to mathoverflow asking about whether the following proof is correct, for example. I'll just observe that MO, while a great community, can not scale to helping lots of people check their homework. For instance, in a Linear class session I might have 20 people, each with 12 homework questions. MO is just not set up for that. Now, sometimes students are sure they got questions right, and usually their certainty is right, so there is no need to ask that one online. And sometimes people can find a relevant previous answer (although learners often struggle to find those, in my experience). Nonetheless, even after taking those out, there are still a lot of people with a lot of questions. > Try to find a community of others online and work with them. Yes, very good advice. I just wanted to observe that while it might work for OP (and I hope it does), it cannot work for lots of people. I don't know what the answer is, and maybe MO could help a lot, but it can't be the answer alone.
