Wow, 50 books does seem like a lot to me! I don't know if I'd be able to read that many books that fast! Lol. What's your favourite book(s) that you've read so far?
Setting a goal and working on it is good because then you have something to work towards and reading all these books will sure make you pre-occupied! I hope that in the end you do achieve your goal of reading 50 books before you go back to school. Your doing quite well at the moment with all the books you've read so far, so keep going!
Take care.
