I think people who go to lecture get to process information
1 time in lecture
1 time in the first read through handout/lecture notes
+ however many times they review
So on the most basic level, to compensate for missing the lecture, I think the main thing is to re-read the handout one more time than you would otherwise if you did go to lecture. That way, you will have gone through the notes exactly as many times as everyone else. 🙂 I think the number of times you repeat a handout (whether by hearing it in lecture, or by reading it yourself) is proportional to the amount you retain, and therefore proportional to your exam results. So instead of reading once slowly, read two or three times really fast and it doesn't matter whether you use review books, or just the handout + textbook as suggested above.
I would suggest going to lecture periodically (i.e. once a week, or something like that) to confirm you're studying the right things. I think the best litmus test to check whether you're studying the right things is to learn the handout for a sample lecture (i.e. read it through carefully once) BEFORE you attend, then attend to confirm you learned the right things. If you did, then you're all set-- if not, just attend a few more lectures until you get the hang of it. Make sense?
I don't personally rely heavily on review books, but I stick with BRS because the print is nice and High-Yield hasn't been sufficient for me in the amount of information they include. I hardly ever use them during the first run through the handout. To me, they're good for:
1) to compare them to the class handout and confirm what topics are important
2) read through relevant material in review book AFTER I've gone through the handout 2-3 times and actually learned it. It's efficient for me, takes about 20 minutes and is just another re-cap
They are more like a security blanket than anything else-- they don't help that much in preparing for the exam, but it's reassuring to see material I've learnt appearing in the review book. 😎 On a final note, I do go to lecture, but for me it's just one more walk through the notes. If I spent the lecture hour just reading through the handout for the day, it would do me pretty much the same good.
