<p>I bought everything for Physics 1A; now it looks like I might have to start over with a new book. $$$ This did not happen with math last year we just kept using an older edition and those starting the series had to buy the new edition.
One thing is, I skipped a quarter of physics and took 1A two quarters ago; not one right after the other. Don't know if that would make a difference.</p>
<p>That is why its best to take sequence classes in one school year to ensure this doesn’t happen.</p>
