Practise material

Can anyone suggest me good practise material that would help me build concepts in PS & DI.
I have completed OG 11 PS&DI and now I am going thru OG10

I find them way too easy and have just 1 month's time before I take GMAT

Regards,
Mani

which is the right usage

"and therefore not subjected to" or "and therefore not subject to"
