What you need: Scroll pen; Jac Zagoory Scroll Pen, $35
Risk level: High
There are ways for you to concoct a pen-based set-up where you attach a sheet of paper somewhere onto the shaft or cap of a pen (or mechanical pencil), but that may be too much prep for some of you. For an easier route, there are scroll pens: pens with rolls of paper built-in. It’s not necessarily high-tech, but it’s a very handy gizmo. Jot down your notes onto the ribbon of paper before you load it into the pen, then pull it out as needed during the exam. Make sure the pen you choose looks like as close to a regular pen as possible.
