Answer to "Is it ok to do OG questions at the end of each Manhattan GMAT SC guide's chapter"

Following is the reply by gparmar16-->www.gmatclub.com to my question "Is it ok to do OG questions at the end of each Manhattan GMAT SC guide's chapter".

  

It can't be stressed enough how effective the MGMAT SC book and its strategies are for tackling the sentence correction portion of the GMAT. I highly recommend continuing what you are doing. Performing MGMAT questions at the end of every chapter along with the assigned problems they give. 

It is true that many of the questions the MGMAT assign have multiple concepts that are tested. Unfortunately any higher level SC question you will get on the GMAT test will have multiple errors. It is frustrating tackling concepts you haven't covered yet, but note the ones you continue to get wrong (before you hit that chapter in the book of course). When you do hit that chapter you can just focus a bit more, knowing you have trouble with those concepts. You may even be able to clear up all the trouble spots on your first run through the book.

Also great idea on getting a list of OG10th questions from the 2nd edition. This is what I did so I didn't exhaust the questions from the OG12th edition. Besides OG10th has twice as many questions. I also recommend answering every OG questions the way MGMAT lays out at the end of their chapters. Identifying the errors in each of the wrong answer choices, highlighting subject-verbs, pronouns and their respective antecedents, etc.

My Question on GMATClub regarding my Manhattan GMAT SC guide study

Well, below is the question I posted on http://www.gmatclub.com regarding my GMAT SC study plan/preparation. I'll post the useful replies or comments when posted by other members.
Actually, I have studied MGMAT SC 4th edition's 4 chapters, and now I am on 5th Chapter (Pronoun) and the previous ones were S-V Agreement and Parallelism. After studying Chapter 3 (S-V agreement), I solved problem sets at the end of the chapter and also attempted OG 12 S-V questions and got 9 out of 11 correct, which is equal to I think 82% (after putting results in Awesome Error Log). Average time spent on each questions was about 2.7 minutes. I didn't have problem with identifying and solving S-V issues in those questions, and could jot down to 2 choices within 15 seconds but after that all of the time was spent on choosing between 2 choices (Actually had problem with pronoun and parallelism or other topics instead of S-V). Maybe, the reason was that I haven't gone through other topics yet.
After S-V, studied the chapter 4 Parallelism and now thinking whether I should attempt OG questions (especially at this time) or not? Also, thinking of whether to do OG for next chapters or to do not.

Whether I should attempt OG questions at the end of each chapter or not? What do you guys suggest?

By the way, this time I plan on attempting OG 10 questions instead of OG 12 (reserve it for later use when done with MGMAT SC or when completed all OG 10 questions), only if you guys suggest to attempt OG at this time.

SC-->MGMAT

Just started, MGMAT SC chapter 1, I gotta say this book is must have for SC ( Sentence Correction). Very well written & organized, it wasn't boring going through the chapter. I do have a Grammar book as a helping book for verbal but things like Brevity, Style and Redundancy are not discussed in grammar books. MGMAT does cover these things and it really makes a lot easier for us to identify clear concise and succinct answer choice. After looking at Kaplan Premier and visiting some forums like gmatclub.com, beatthegmat.com and manahattangmat.com's forum It's clear that we must follow the patterns as follows when dealing with SC questions.
1.Correctness
2. Clarity
If an answer choice has a technical grammatical error like Verb/Tense, Subject/Verb Agreement, Pronouns, Modifiers, Parallelism and Comparison related errors can not be accepted at all even if a sentence looks wordy or awkward. Clarity matters when we have to choose between two grammatical correct choices then should go for the clear, short and succinct one.
And yea Correctness can be subdivided into two categories,
1.Correctness related to Technical Grammar Rules ( mentioned in paragraph above )
2.Correctness of Idioms and voice ( Active voice is always preferred over passive voice) and also gotta take care of Mood ( Subjunctive & Indicative )
I think that's enough for today...enough studying..now gotta listen to some nice music yayyy
