Natasha, did you purchase the book that I told to you for the Quant?

Here the link: https://books4u.in/book_detail.php?book_id=1494
Book Name: Quantitative Aptitude by R S Aggarwal

You need not to do all the topic from this book but yes it covers 90% of GMAT quantitative material and helpful for the person to brush the quant's basic or to learn them from scratch. Also it has plenty of questions to do, so it will help you to do practice. Also it is very cheap and easily affordable in India (if you are somewhere else then you need to check on ebay or something).

I did my permutation, combination, probability and mixture problems from this book only.

No need to spend your hard earned money on expensive books or materials.

For SD, I have prepared a doc that contains the basic of SD and around 15-20 question (collected from this forum).

For inequalities, I prepared by reading posts on this forum only. Also, I referred some inequalities posts from Dr. Math forum: https://mathforum.org/dr.math/

Here are some links related to inequalities that I studied. Yes I also learned graphing of inequalities but may be you need not to learn that.

https://mathforum.org/library/drmath/view/65229.html
https://mathforum.org/library/drmath/view/53148.html
https://mathforum.org/library/drmath/view/57380.html
https://mathforum.org/library/drmath/view/53065.html
https://mathforum.org/library/drmath/view/52999.html

The above links can clear the basics of inequalities. For more you can search on the Dr. Math forum or may write at the forum.

If you some specific problems, then you can post on BTG forum. There are many people to help on Quant section.

Note: Not to forget OG 11.

Here the document attached with this post. It covers the basic of Mean, Median and SD. Also contains 11 problems based on the above mentioned topic.

For the solutions, I didn't prepared any doc, just solved them on rough sheets. However, you can find these already solved on this forum. Just copy the question and search at this forum. You will get the solution.

Hope it helps...

WOW! Thanks codesnooker for sharing these notes with the forums.
They are fantastic.
@SD: It's always better to know how to calculate standard deviation but I am sure GMAT never asks to actually calculate SD. (it's bit complicated) GMAT tests your familiarity with the subject..

Thanks anyways.

Moving it to Math section.
Eric might add it in resource directory. :)
