I don't think I'm ever reading less than 3 books at a time. I've had up to 6 going on once several times.
Pretty much all the time. I very rarely read two books equally. But I'm really bad at being critical about books, so if I really want to read one book over another, it makes me realize that maybe the one isn't that great.
And I really don't have a problem picking a book I've neglected back up and remembering what's going on unless I don't read it for over a month. And although that does happen occasionally, it's not a frequent thing considering how many books I read at a time. I'm only doing 3 right now: one I'm rereading, one is in a series that I'm reading and one is an ebook that I have on my phone that I can read in my spare time when I don't have a book on me.
I try, but in the end I usually don't end up finishing any of them. I can't hop back and forth. I've found so many old bookmarks halfway through books on my bookshelf. When I can't remember exactly what happens it saddens me and makes me feel like I wasted my time in the past because I have to start from the beginning again. *sigh*
I try to read one book at a time but there is SO MUCH TO READ.
I usually have 2 at a time, maybe 3, but my max was 9.
Right now I'm reading Sherlock Holmes with one Math book, one Psycology book and House Rules by Judi Picoult.
I've slowed down in my reading as of late, but back in high school my classmates used to tease me that I had a different book in every class. Probably because I did. When I really needed to, I could read around five or six books at one time. I'm a pretty quick learner so usually a book takes me no more than two days to read, so I often had to have a lot of books to keep me busy.
When I could I used to go to the library and check out about 40 books. Then I'd pick about 8, set them on my bed around me, and start reading one. I would go in about 50-100 pages then set it down, grab a snack then read another book. Rinse and repeat. I could usually finish 4 books in one day that way (of course that was before college). Now I just stick to one because of time purposes, but I never had problems keeping track of plots or neglecting books.
