Is dat destroyer 2007 just as good as the 2009 one is i could get it for 40$

This forum made possible through the generous support of SDN members, donors, and sponsors. Thank you.
the 2007 destroyer has a lot less questions per section than the 2009 or 2010. I'd say atleast a 100 or more questions are in the newer edition.
 
Here is what I have found (feel free to correct any mistakes):

DAT Destroyer 2007
- 186 organic chemistry questions
- 184 general chemistry questions
- 313 biology questions
- 153 quantitative reasoning questions

DAT Destroyer 2008
- 186 organic chemistry questions
- 189 general chemistry questions
- 324 biology questions
- 153 quantitative reasoning questions

DAT Destroyer 2009
- 210 organic chemistry questions
- 212 general chemistry questions
- 350 biology questions
- 153 quantitative reasoning questions

DAT Destroyer 2010
- 232 organic chemistry questions
- 242 general chemistry questions
- 377 biology questions
- 156 quantitative reasoning questions

So there are more problems in the latest editions, but the real question is, are the new problems just repeats of the originals (i.e. different versions of the same type of problem), or do they cover new material that the original DAT Destroyer completely missed?
 
Is there a way to just get an update by paying less money than the full price?

Thanks a lot. I'm only using for the cDAT so bio and gchem. I haven't decided if ill write the american DAT.
 
The destroyer is deffinetly not a repeat every year. more and more questions are added and the more questions that you can solve, the better that you can do. When I bought my 2009 version, It had brand new biology nd organic chemistry questions that were not in any of the older versions. I took the DAT and those new questions really reallllly prepared me for the orgo and bio. If I were you I would do the 2010 book and not conserve money right now because dental school will cost you plenty and you want to make sure you get into the cheapest one. The newere the edition, the more questions, the more you are prepared, hence the better you will do.

Look, I have both versions. The 2009 is substantially changed from say an 05 or 06 but it is doable from an 07. Save the extra money and get the 1001 O chem book from EK if you want tons of practice for O Chem. The topics presented in the old editions of Destroyer have been presented. The new ones are just a little more problems. Just make sure you know the concept. Whether you are doing 2 examples or 5 examples of the same reaction doesnt matter if the end result is the same.
