I can ask questions in Google.

Quora I guess is the best place to ask questions.

It seems to me that everything depends on your questions. I often ask household questions on the Internet, but if I'm interested in some scientific question, then I'm looking for accurate and truthful information here https://studentshare.net/. This portal is designed for students who need information on any subject, help with homework, there are professional answers. I know that the Internet has a lot of conflicting information, so I try to trust only proven sources.

It depends on what kind of questions do you have. If it is related to studying, especially Math, it's better to talk with real teachers or professors. For this, I can recommend you to check Easy Math Tutoring service - https://www.ezymathtutoring.com.au/. For sure they will help you to understand everything better!
