Hi NJSS,
Thanks for the observation. I just flipped through the last few problems in
OG 10 PS and you're right, they don't seem all that difficult.
When I was doing PS and DS in OG11, I could definitely notice a trend: the last 50 or so PS were significantly harder than the first 200. The first 100 or so problems are just too easy and then they begin to get a little harder (not by much though). DS was the same way.. the last 15 were tough for me.. i got 6/15 wrong.
RCs get longer as you go through the section. SCs progressively get trickier. CRs are consistent (in terms of difficulty).
Hi Vivek,
I have worked through OG11 but haven't done enough of OG10 to be able to say whether both are necessary. I am doing both just to be safe (since they are realy gmat questions). I know there is some overlap. Also in
OG 11 there are:
250 PS
155 DS
140 RC
128 SC
124 CR
Thats a lot fewer than the OG10. The new edition does however, have much better explanations.
Vivek, I'd like to know what you think about the level of difficulty in quant in OG10 (if you've already completed it) : in your opinion, does it get progressively harder? Would you recommend using the "database" to attempt only hard/medium questions by question types?
Thanks
