You are trying to get it right, but you might not. Maybe though you got almost there. If you got almost there, don’t cover your tracks. Don’t make it seem like your work is perfect. Make it very easy to see what you did and why. Make it easy to see where you are wrong, if you are wrong. That way those who come after may be able to succeed where you failed, or perhaps avoid a blind alley, if that is where you have strayed.
All the steps in the argument should be clear. All the language should be defined so a thirteen year old can understand it.
Don’t claim confidence you don’t have.
Those points you are unsure about: reveal that you are unsure. Make an honest attempt to learn the truth. Do not try to persuade, seduce, or convince.
We are all in this together, there is no room for tricks.
