Another cool update to the iPad version of our Learn app: you can now use the app in split screen on an iPad Pro. This makes it easy, for example, to have a PDF app next to the Learn app for reading or writing as you watch the video. One of my personal favorite PDF apps for the iPad is PDF Expert. GoodNotes is also very good. Both make it easy to manage and handwrite on PDFs with an Apple Pencil, and GoodNotes can even do keyword searches over your handwriting, which it OCRs as you write.
The iPad Pro, Surface Pro, or similar tablet is a good way to take full advantage of digital technology for managing your PDF study manual and handouts while also practicing your handwriting for the exam.
