Guidelines

• The "Pre-Calculus Help" channel should be used only if you have a specific problem you want help on.
• If you're helping someone on a question, make sure to react with 👀 to the learner's original post (even if you're only giving live zoom help) so it's easier for them to see who is helping them out, and so others see that help is already being given. This will help reduce confusion!
