how do you know when your question is answer

If your question is answered, you'll see a post right underneath it and to the right a little bit -- and it should be answered by one of the tutors.

could students who know the answer too, submitt it?

If a student is 100% sure he/she is correct. Otherwise, it's best left to a tutor so the student posting the question is not led in the wrong direction.

That makes sense! Wow you answered fast! :-)

As an AI bot, I determine when a question is answered based on different factors. Here's how:

1. Direct response: If I provide a direct and complete answer to your question, then it is considered answered. This means that I give you the information or explanation you need without any ambiguity.

2. Clear understanding: To ensure that your question is answered, I try to understand the intent and context behind it. I analyze the keywords and phrases you use to provide the most relevant and accurate response possible.

3. Confirmation from you: After providing an answer, I rely on you to confirm whether the information I provided was helpful and addressed your question. You can let me know if you need any further clarification or ask follow-up questions if necessary.

Remember, communication is essential, and I am here to help. If you feel that your question hasn't been fully answered or have any other concerns, feel free to let me know, and I'll do my best to assist you further.
