Hi kshitij_ipu,
Your scores on the most recent GMAT practice tests are most likely within the range of what you would achieve on a real exam - GMATPrep is very accurate.
With that said, I think it's time to try out ManhattanGMAT's Sentence Correction and Reading Comprehension guides if you are having particular difficulty in these sections. This will provide you with a better foundation that you can use to perform better on these sections of the exam. As for quant, I would recommend looking into
ManhattanGMAT's Data Sufficiency Workshop. In this workshop, you will be able to learn advanced techniques that will help you save time on data sufficiency problems, thereby allowing you to use more time to tackle more difficult problems.
Now, onto your other questions that you posted:
1. The Sentence Correction Guide comes with 6 ManhattanGMAT CAT Exams as a complimentary resource. Additionally, it comes with a Sentence Correction Question Bank as well. Keep in mind, though, getting the Reading Comprehension book does not entitle you to ANOTHER 6 exams - six is the maximum number we can provide to anyone who uses our practice tests due to the size of our question pool.
2. The Challenge Problem Archive contains some VERY difficult questions - many of which are 750+. in difficulty. I think that your time would be better spent enrolled in the Data Sufficiency Workshop because you'll have proper guidance from an Instructor - answering these challenging questions without the aid of someone who knows how to decode what they are saying might not result in knowledge growth.
3. ManhattanGMAT Products are available at the
following locations in India. Of course, you can always buy the guides at our
Online Store or from
www.amazon.com or
www.bn.com.
Hope this helps!
