Comparing two PDFs to easily see the differences between them
Hey guys, so, i'm with the following situation:
i bought a material (PDF files) from my teacher to study for a specific test. Then, some months later (The test had not been performed yet), this same teacher did another material (the same material i bought in the beggining, but with some updates). i have access to the new material, but i don't wanna throw away the old one, cause the old one has a lot of marking and notes that i made on it, so i would like to find a good way to compare the content of these two PDFs to check if these updates that the teacher done are a lot of things, or just small things that i can do notes of it in the old version. Any ideas?
Thanks in advance
