So my friend is doing medical from it's a College near South Durham. It's a very good College. Anyways, so she was telling me how the seniors, they do lagging. So they make a PDF, and this send it to the juniors. And basically, it's a whole last period, like 30 to 34 pages. And there are certain things, certain rules. And one of them, she showed me this. She was like the PDF for so long
