Reddit reviews Real SAT II: Subject Tests: 2nd Edition

If you are talking about this book, this book, or this book, they contain all the same tests.

If you want more exams, get the subject specific Official Guides in Math 1, 2, Bio, Chem, Physics, WH, etc.

If the exams you're preparing for don't have specific Official Guides and you want 1 more real exam, you'd need to get this book.

Yeah they don't have Lit tests on that site.

To prepare for the SAT Subject Test in Literature, I recommend using the Ivy Global guide for strategy and 6 extra practice tests, and using the 4 official tests that are available as diagnostics to gauge your progress along the way.

1. Ivy Global's SAT Subject Test in Literature: Study Guide & 6 Practice Tests
   
2. The Official Study Guide for ALL SAT Subject Tests
   
3. Real SAT Subject Tests (2006)
   
4. The Official Guide to Sat II: Subject Tests (1994)
   
5. The College Board Achievement Tests: 14 Tests in 13 Subjects (1983)
