I'm trying to find a program, or set of programs, that will allow easy markup of student assignments submitted as PDFs. I'd like to include more complicated math with this markup.
I've tried pen tools, like the one in Acrobat DC, but they tend to be too messy to read. (I have an old Bamboo pen tablet which isn't terribly sensitive.) Right now my best setup is typing in Word using MathType for the math and using the snipping tool to transfer it to the PDF in Acrobat. It's pretty clunky.
