This is my most popular product ever! The font is large and it is easy to navigate through the document as a google document. It is nearly 500 beautiful pages to guide you and to check your answers! Each exercise has its trivium level, any extra information if needed, and the answers (even if it is a diagram or if Mr. Henle did not do it).  As a bonus, if something is unclear, you can write a comment on the google document or send me an email to ask me about it. :) It is well worth the price!
