Cliff is important or Barron book before you start studying any notes.
If you insist on just readign notes.
You can study Feralise along with for Russel notes.
Russel notes are very neat! It's the materials from Cliff +Barron put in around 150 pages, but he made them look simpler.
as for Alan's notes, they are best read after reading Cliff.
but Russel notes can work without Cliff, I just don't remember from where I downloaded them, someone someday posted them.
Edit: I found them on google when I wrote this:
Russelldw DAT Notes
But honestly,
If you read cliff+youtube+destroyer or even just the detailed notes and then write your own notes afterward in an organized way either on Microsoft word or by hand, this is a better way to retain the info.
