GMAT QUANT PRACTICE

Practicing quant from OG 12. Have done it earlier though.... doing again to analyze my weak areas. Conclusions till now:

* SET theory - Concepts need to be revised... always getting stuck.

SET theory in manhattan guides is not very detailed & does not contain the variety of questions we might see on gmat. This is what i feel...... may be i have to refer to sum of the CAT material.
