New Grading System...

I decided to grade my books differently like the A B C D F thing. Before I just randomly chose a grade, now I going to grade by...
Plot, Description, characters, How Fast the story is, and the last one cover (Iknow it is stupid, but I always like reading a book with a good cover.)   I am going to use this format on the next review that should be coming up very soon. It is going to make my grading way more strict, because I usually never give anything below a C but I might have to soon.
