Every one of these is normal and every one of them is easy to avoid. None of them will end your conference.
Saying "I" and "you". Delegates speak in the third person. Speak of yourself as the delegation. Speak of others as "the honourable delegate" or "fellow delegates".
Forgetting to address the chair and the house. Delegates address the chair and the house before their speech. Make it the first thing you say.
Raising your placard straight after a speech. Placards stay down until the chair asks for them. Wait for the chair to ask, then raise it, then wait to be recognised.
Speaking too fast. Nerves make everyone speed up. Slow down and leave a pause between sentences.
Saying "Third World Countries". Say "Less Economically Developed Countries".
Making a speech inside a point of information. A point of information must be a question. One short statement may come before it. Using it to attack a resolution instead of asking a question is out of order.
Arguing with the answer. There is no dialogue after a point of information. If a follow up is allowed, the chair offers it and checks the delegate on the floor is willing.
Inventing a point. If you are not sure a point exists, describe what you need in plain words instead. Getting the wording of a real point wrong is a mistake and chairs will work out what you meant. Inventing one is not allowed.
Interrupting a speaker. No point may interrupt a speaker. The one exception is a point of personal privilege about audibility.
Raising a point during voting. All points are out of order during voting. The one exception is a point of order about the conduct of the vote itself.
Saying "motion to move directly into voting procedures". The correct wording is "motion to move to the previous question". Chairs are asked to correct it.
Expecting friendly amendments. There are no friendly amendments. Adopting an amendment without a vote is out of order. Every amendment is put to a vote, even a one word change.
Expecting an amendment to be too small to bother with. A spelling or grammar mistake is the exception. The chair changes those directly and tells the house. Everything else is debated and voted on.
Assuming you can abstain. A delegate who answered "present and voting" at the roll call may vote for or against only. See Present and voting.
Clapping at the wrong moment. Clapping is only in order when a resolution as a whole passes. It is not in order after an amendment, and not when a resolution fails.
Treating a failed resolution as the end of the topic. Each resolution is debated in a vacuum. One resolution passing or failing does not decide anything about the next one on the same topic.
Copying clauses. Copying clauses from previous resolutions is plagiarism. Rephrasing something you found in a book or online is still plagiarism. Common clauses, meaning the standard opening and closing wording, are the exception. Quoting is fine when it is cited. See Plagiarism.
Letting an artificial intelligence tool write it. Using AI to write a full clause or a full resolution is plagiarism and is not allowed. AI is not a source, and anything it produces has to be checked. Your own school decides whether you may use it as a tool at all.
Writing clauses your committee cannot act on. A General Assembly cannot impose sanctions or deploy troops. Reword during lobbying rather than losing the resolution to a motion to refer it to another forum.
If your resolution will not submit. The format is checked before a resolution can reach the chairs. It needs at least one preambulatory clause and at least one operative clause. Every clause needs a starting phrase and a body. A list of sub-clauses must have at least two items, never exactly one. MediBook explains what to fix. Correct it and submit again. See Resolution format.
Sending your position paper the wrong way.
In MEDIMUN, position papers are submitted in MediBook. A position paper sent by PDF, by email, or on paper is not accepted. It will not be read. It will not be marked. The delegate will not be considered for an award. See Position paper rules.
Submitting your position paper late.
In MEDIMUN, a delegate who submits a position paper late cannot receive an award.
Leaving parental consent to the last week.
In MEDIMUN, a delegate whose parental consent is not complete is not allowed on the premises. Send it to your parents or guardians as soon as you are assigned. See Parental consent explained.
Arriving without a device.
In MEDIMUN, a delegate without a device cannot take part in debate properly. MEDIMUN does not provide one. See Device and technology policy.
Eating during debate. Eating and drinking during debate is not in order. Water is the exception.
In MEDIMUN, ordering food is not allowed. See Code of conduct.
Leaving without permission. Ask the chair before you leave the room during debate.
Not telling the chairs you arrived late. A delegate who arrives after the roll call must tell the chairs.
Missing the morning register.
In MEDIMUN, you are scanned in each morning of the conference. See The morning register.
Working with a group you never declared.
In MEDIMUN, all alliances are declared in MediBook and the chair enforces this. Declare yours as soon as it forms. See Forming and declaring an alliance.
If you are unsure whether you have made one of these mistakes, ask your chairs. A delegate who checks is not the delegate chairs worry about.
