Jeff Sackmann Challenge Set Review ?

by GoBlue » Tue Nov 09, 2010 8:20 am
Hello,
I am stuck at 45 Q and want to take it to atleast 48. I am screwing up big time in DS for sure but also Geometry and Number Properties. I have MGMAT Number Properties but I was wondering if anyone has gone thru Jeff Sackmann Challenge sets.
- If you have, which ones are highly recommended.
- I know each of these sets is $ 20 bucks, but do they have good explainations ( a little pricey )
Any review / info on them would be appreciated.

I have practiced on the advance word problems, algebra, and DS question sets. Most explanations are pretty good, but there are definitely a few that are somewhat questionable. Overall, I would recommend the set if you need more practice beyond OG.

PS. I did reach 48 on my last GMAT attempt.
Yep.
