chxin They have changed quite a lot in my opinion, if that is the only one you have then use it but imp I think there are more better ones that are new, btw most people do Jac tutoring we all know that and if you follow the same path as them what gives you an advantage?
Jac may be the most popular but it isn't the best neither is spectrum.
If you are rich (Probably not) then you can try Henderson's it may be $75 per lesson but it has a very high success rate of you getting an offer at a SEHS school including MHS

asianasen I did a Jac math test set 23 for fun on this. My score was 43/50, it's simple but I'm a bit rusty so that's why I messed up. I jus wanna see if any one else wants to beat my score.
