Thank you to Hussain15 for pointing out a huge typo I made - I have updated the PDF.
Shooting for perfection :)

P.S. Thank you to Dreamy for help as well.



thanks so much. I am having trouble with understanding the method in slide 62, the one with the advanced method for finding the number of all possible
factors. can you explain it please? thanks!!



You may get better luck/success if you actually paste the contents or take a screenshot if it has formulas/other items that you can't easily copy.


yes of course, thank you.

 Advanced method for finding the number of all possible
factors:
 Write out each prime factor and their power, for
example, 12 can be written as follows:
 2^2
 3^1
 5^0 etc (all other primes will have a zero power)
 Add 1 to all powers and multiply them: (in this case 6)
and that’s the number of factors (1, 2, 3, 4, 6, 12)
 Prime Factors of 462 = 2^1, 3^1, 7^1, 11^1
 Total number of factors: 2x2x2x2 = 2^4= 16

Is the only way I can have access to all flashcards broken down into topics on the app is to buy the full version of the app correct?

Could someone please elaborate on why 2x-6+sqrt(2-x) is not the answer in addition to sqrt(2-x)?

This is on page 28.

Am i a missing something?

Thank you.

Thanks for posting. This question happens to be a GMAT Club Tests question, so it is a bit tricky and has a few concepts wrapped in a seemingly simple question. You can find a long discussion explaining each step here:

bb thanks a bunch! I was looking for this discussion.

As a side note, just wanted to add a small comment. On my recent GMAT, i had to make an actual calculation of the STDEV. However, the STDEV formula was provided. - I didn't expect this concept to be tested and got quite nervous despite the fact that question, given my finance background, was not very hard. Thus, i believe sooner or later GMAC will start to explicitly test this concept.

Thanks for the feedback from the trenches!
They have been mulling over the DTDEV for a while. They have not asked to memorize the formula but they do ask you to understand the relationship of the STDEV and Members in the set, as well as mean, mode, median, etc but these questions are rare.

Hi

Just wanted to say thank you for putting this together, certainly is of much help!

I'm using the app and going through the pdf pages, I can see there's probably about twice the amount of flashcards in the pdf that in the app, is that correct? Is there a way in which I could upload the missing ones?

Thank you so much in advance for your time,

Best

Hello,

This is Nisha Patel from Surat city of India. Right now I am studying in Cambrian College, Ontario, Canada.
Let me to share my experience on an IELTS coaching class in Sura , it may help others to pursue their career in Canada.
I have enrolled for my IELTS classes in Surat with Mango Education & Immigration Consultant, Station Road, Surat.
The IELTS faculty at Mango are the best and took the deep personal interest in me as I was from Gujarati medium background during
my 10+2 schooling in Surat. They have the best library with very knowledgeable books and literature, they not only provide IELTS coaching, they also guide me for my Canada study and immigration. My IELTS result is here as under:

Reading: 8.5
Speaking: 8.0
Listening: 7.5
Writing: 9.0
Thanks to Mango. Hope, it help others in Surat.

Thanks,

Nisha Patel
Cambrian College, ON - Canada.
