2 weeks to go and lost :(

Infact even the questions in OG 11 seem much easier than what I faced on the prep test?? Have I been preparing the wrong way?

Hi

Any help is appreciated. Every day counts now! :(Princeton practice material looks very simple compared to the actual test

Go for the official questions! Princeton has been evaluated as too easy many times, including in our forum's official review of books. Besides, as a rule, there's no better practice out there except for the OG: questions are clear cut, answers cannot be debated...
Some people have argued that even the questions in the OG are a bit too easy as compared to what they saw on test day, particularly for quant. I can't say if that holds true for quant, since I didn't practice for that part at all. I will say that verbal questions followed the exact patterns that I saw in the OGs!
If you really feel unprepared, then reschedule. You don't want to go there and just be scared; it's going to affect every part of your experience!

Thanks DanaJ. Too late to reschedule though.. Taking the OG more seriosly and concentrating on my weaknesses for now.. Cant think of anything else to do

There isn't much time for anything else, but given the constraint I'd say you're taking the right steps. Don't get discouraged, it will only add to your anxiety! Remember that, no matter what score you see at the end of the test, you can always retake! All the best on D-Day!
