OG 11 plus OG 10 [#permalink]

Hey guys, I am in need of some advice regarding the two OG editions.

I began my prep w/ OG 11 and did all the questions. Today I came accross OG10 at a used bookstore for \$7 and decided to buy it. I know there is plenty of overlap, but the OG 10 has a lot more questions in it, so there are bound to be different questions. My question is, how do I use OG10 after having completed OG11? (My target score is 750). For Quant, should i do the last 100 PS and DS only? I don't mind seeing some questions again as long as they are fairly challenging and serve as good practice. What about verbal? Please Advise!!!!

Thanks

Somewhere on this forum there is an access database with all OG10 questions categorized by type and level of difficulty...

I have OG11 & OG10... I am done with OG 11 and using that access database as a tool to improve on my weaknesses... so you can pick hard questions or specific types like Inequality and solve...

Yes there is some overlap and hence I find this approach better.

Vikram,

Thanks i just found the access file you referred to. It seems to be a great resource! One quick question though, do you think its better to break it down by hard questions for each question type, or just do a mix of different hard questions in one sitting?

Careful these question ratings are one person's subjective opinions. They are not released by ETS. I found many questions that were miscategorized.

Do what works best for you.... at the end of the day, HARD/EASY/MEDIUM in that database is still someone's opinion.. not official ETS tags... a Hard may be really easy for you..

I did them (still doing) topic wise (mix of hard + medium) as I discovered my weak areas.... like pick 10-15 questions from 2 topics and try solving them in 20-30 mins.

Thanks for pointing that out. I will be more careful in selecting practice problems.

Approaching OG 10 after OG 11 [#permalink]

Dear YB,
On a related note...just started off on OG 10 bacwards on the PS section...and found out that (IMHO ) they are pretty easy....just got 4 out of 50 wrong...so I guess that the idea that OG sections move from Easy to Hard is a myth...more like if u have a specific weak areas, the most diff problems in the weak are are clustered around the end...realized that for number prop and perm/combo...so my ten cents worth - check out what kind of problems you are weak on...mark them out in the OG and work on them at a stretch separately...

And do let us know whats the diff level of OG 1o vs 11

Cheers!

Rgds,
NJSS750

Hello buddies,

I have OG 10, is it necessary to buy OG 11? Do you recommend it? What do you think?

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

Dear Yb & Jinesh,

Thanks for the inputs!

Well, I have done OG 10 quant once & I think the quant sections present harder questions towards the end but definitely not as hard as the hardest in the test. Relatively, OG quant is easier than that in the test, so it would be better not to consider OG as the only quant source.

Thanks Vivek!

Kayser,
I know there are a lot of different questions but not sure exactly how many. I guess your decision to buy the new edition should depend on when you are planning to take the test. If you have enough time, there's obviously no harm in studying more(especially if its official material).

I think its important to also study some more difficult material for quant in order to master the concepts. I would advise dedicating some time to taking challenges or kaplan800 questions.

Hi guys, I have OG 10 (havent gone through it yet, saving the best til last) but I was wondering whether there is any point of me buying the 11th edition, are there different questions explanations etc, or would I just be wasting my money and time?
