Does the LNAT publish numerical Section B bands?

The public LNAT pages linked here do not give Section B a separate numerical score or publish a universal banded rubric. Oxford publishes a training-session description for prospective essay markers that discusses marking criteria, but the page does not disclose those criteria or a scoring scale.

Section B lasts 40 minutes and asks you to answer one of three questions. Participating universities receive the essay with your Section A result, and each one publishes a different position on reading it.

Can Margin give an official LNAT mark?

No. The six browser checks name question terms your draft never uses. The AI marking sorts up to four criteria into four band words Margin wrote. Argument and style are the skills LNAT publishes; structure and use of material are ours. Neither predicts an admissions decision.

The result is an independent practice diagnostic, not an official LNAT mark or a university rubric. The six checks run in your browser. Marking sends your draft to Vercel’s AI Gateway, which tries up to two models in turn until one replies.

A descriptor tells you what a marker looks for. It does not tell you what to change in the essay in front of you, which is what feedback on your own draft is for.

Where the descriptors stop

No published descriptor turns a Section B essay into a number. The number on your LNAT report comes from 42 multiple-choice questions. 10 of the 83 questions on the practice page are free. Founder access is £25 for the other 73, each with the passage sentence your answer turned on.
