Lectures often cover things that aren't on the handout: an extra example, a clearer definition, a hint about the exam. If you type those notes directly on the PDF, they stay next to the material they explain.
Before class
Open the handout in Type PDF and set a zoom level you're comfortable reading. If the margins are narrow, pick a smaller text size now so you're not adjusting it mid-lecture.
During the lecture
Click beside the paragraph, problem, or diagram being discussed and type. Write down what the handout doesn't already say, such as:
- "Only use this formula when speed is constant."
- "Ask why case 2 is different."
Keep notes short. You're adding to the handout, not transcribing the lecture. If there's no room near the right spot, put a short numbered note in the nearest empty space instead of covering text you'll need later.
After class
While it's still fresh, expand any abbreviations, move notes that overlap the handout, and resize boxes where text is cut off.
Then download an Editable PDF so you can reopen it in Type PDF and keep adding to it. Name it by course and date (bio101-oct-4.pdf) so it's easy to find before the exam. Type PDF can keep a draft in your browser, but download a copy so you don't lose your notes.
