Hello there,

Since I have been preparing myself with the self studying approach, I am trying to compile all the books that people here think is a must have or a nice to have during the preparation for GMAT. I read on the other day that the OG 2015 from GMAC is totally necessary for this preparation and I acquired it but it seems it is just a bunch of questions (900) thrown in the book for us to practice, with no theory, strategy or anything else. So I started to wonder if it is really necessary since prior to that I have been studying with Manhattan guides and they seem to be quite good + Veritas Prep (Question Bank and Prep Tests)...It just seemed like a step back.

What do you guys think?

The 2015 OG (and the new 2016 version, which will have some new questions in it) are produced by GMAC itself and they contain questions that once appeared on the Official GMAT. In that way, those questions are arguably the most realistic questions available. While you don't *need* either of those books for your studies, many Test Takers use some version of the OG during their studies. I am a fan of those books.

It's worth noting that GMAC is NOT in the business of teaching you all of the 'secrets' to beat the Test, so the subject matter is handled (mostly) in an academic fashion. If you want to learn the tactics, patterns, secrets, etc. that can help you to score at a high level on the GMAT, then you'll have to invest in other resources.

But when it comes to doing practice questions, stick to official GMAT questions. The official GMAT questions will help you get used to the language of the GMAT, and also allow you to see the pattern and style of the GMAT. The official GMAT guides is an excellent place to start, if you need more recent official GMAT questions then use the GMATPrep Question Pack 1 and for computer adaptive tests use the free GMATPrep software and the Exam Pack1. I cannot emphasize how important it is to stick to official GMAT questions.

The upcoming GMAT2016 book (which will be released in June) will include some new questions and will likely "shift" the remaining material around a bit.

Hi Rich and Dabral!

I will sitck with the OG for getting familiar with practice questions and different topics that might actually appear. I have been using MGMAT guides and some Prep Tests and Questions banks from Veritas

When practicing OG questions, do you guys think I should time myself while doing them ?

Thanks again!
Cheers

If you're still early on in your studies, then you should be more focused on learning the material, tactics, patterns, etc. and practicing everything correctly. If you're not comfortable with the 'work' that you have to do to answer a GMAT question, then forcing yourself to try to do that work quickly will probably NOT help you. Speed will improve as you continue to practice and hone your skills.

If you think that you know the material well-enough, then adding in the 'time pressure' would be the next step.

I started an Error Log, but I don't know what exactly to do with it. I finished the first 100 questions from the OG, marked my mistakes, their types, concept involved, so I could find patterns and then I consult the MGMAT Foundations of GMAT Math for getting the concepts straightened up..Do you guys think this is good approach ? Should I try any more CATs any time soon ? or just wait for until getting all 900 questions from OG done ?

Hi Rich, se have exchanged some emails a month ago.

Your prior posts don't provide much in the way of specific information about how you've been studying. If you can answer a few questions though, then I'll be happy to advise:

1) How long have you been studying?

I have been self studying for about 4 months all told, in an average rate of 1:30h per day.

2) How have you scored on each of your CATs (including the Quant and Verbal Scaled Scores for each) ?
official GMAT: 400
CAT 2: 560 (Q32 V35)
CAT 3: 560 (Q38 V29)

3) When did you take each CAT? Did you take the ENTIRE CAT each time (including the Essay and IR sections)?
Yes, took them entirely each time. My studies are now focused on Quant now, since a I am trying to follow this study plan I have found here.

...it recommends to take it partially...skip IR and essay

4) What is your goal score?
My goal is the everyone's favorite: 700

5) When are you planning to take the GMAT?
I am not sure when to take it again, I was expecting the get a good result from my next CAT first.

Hi Carlos,

I didn't make the connection between this post and your prior emails.

Regarding your last 2 CAT scores, I'm a bit concerned by the "swing" in the Quant and Verbal Scaled Scores. This implies some inconsistencies on your part in how you handle those two sections of the Test.

I'm actually MORE concerned though at the idea that you'd be skipping the Essay and IR sections during practice. You WON'T be skipping those sections on Test Day and if you're not prepared to face them (by practicing them NOW when you take your CATs), then you'll likely find that you get really tired during the Verbal section on Test Day and that your scores will likely drop relative to your practice CAT scores.

Hi Rick,

Thanks for your reply. It was just a curiosity, If you would like, search for my emails cfranciscopenteado@yahoo.com.br , we have exchanged some emails because I was (and am) interested in having some more strategy guidance, but first I am noticing I need to get some topics and concepts clarified. You mentioned some interesting modules that can be useful!

In fact, I said I took 1 official GMAT and 2 CAT's, in all of them I did the IR and Essay, those are ok, on average. What I was saying about this was that I am using this study plan I found: gmat-study-plan-how-to-start-your-gmat-prep-80727.html

Don't know if it's good, but I have decided to go with it. I noticed I was being a bit lazy skipping some mistakes I though would not come back, but they do! So I am using the CAT's and OG to check my weaknesses so I can diagnose myself.

Think this is a good approach ?

Thanks

Cheers!
