You probably don't want to as there is significant overlap between OG 10 and GMAT Prep. Not recommended if you plan on using GMAT Prep.

For OG 10:

Strengths:
1. More questions - 1,400 questions vs. 900 in the OG 11 and OG 12
2. Price - right now it is under \$10 with shipping for a used copy
3. Not too much overlap with OG 11 or OG 12
Weaknesses:
1. Significant overlap with GMATPrep and PowerPrep. Also some overlap with ETS paper tests is reported.
