A perfect set of reference books for exam preparation. - Title: Agarooth's Comprehensive Lectures & Q&A - Number of books: 9 - Genre: Qualifications/Certifications - Format: Reference book Thank you for viewing. There are almost no red sheets. There are a few. I looked through them quickly and found no writing, but please understand that I may have missed something. They are mostly clean, but one book has a small tear in the cover.
