<p>I like Dr. Chung’s too. That being said, I scored a 610 on the May SAT (and quite a bit higher in the other sections) so I wanted to bump up my score as much as possible. I got 640 on a BB test before I started Dr. Chung’s and after about 10 practice tests in it and the 50 tips I got 730 on a BB test (or was it 740?). Either way, it helped me a bunch… but I think I would’ve benefited from it more if my score was a little higher to begin with. So if you are scoring below 650 then it’s probably not a good place to start.</p>
