Math Challenge (this forum) vs Kaplan 800 vs Kaplan Math

Question

I want to compare the math part among those three sources:
+ Math Challenge (this forum) 
+ Kaplan 800 
+ Kaplan GRE&GMAT Math Workout

Please tell me which one is the "hardest"
Thanks.

Paul · Answer

1- GMAT challenge from this forum
2- Kaplan800
3- Kaplan GRE/GMAT

Toughest though are problems posted by Akhamai in this forum or "Manhattan GMAT problems of the week"

I have a week to go before my GMAT and I am looking to get in the 600s (700 isn't realistic at this point). Would the Math Challenge or Manhattan weekly problems be over my head? I was going to primarily stick with Kaplan 800 and the ETS tests but I am open to any suggestions.

I did a search and I couldn't find anyone names Akhamai or any topic with "Manhattan GMAT problems of the week"

Can someone point me a clear direction?

Well, I went to this website: https://www.manhattangmat.com/ And I think I found it. It is on the front page.

An example of 5 problems posted by Akhamai (I'm always marveled by the way he solves problems):

https://gmatclub.com/phpbb/viewtopic.php?t=4188
https://gmatclub.com/phpbb/viewtopic.php?t=4173

This is also a post whereby he answered one of my own probability problems with such simplicity and grace:

This is where you will find Manhattan GMAT problems of the week:

Those manhattan GMAT problems used to be posted here every week for discussion. They are always good and challenging math material

Paul · Answer

I would suggest you to join the next challenge next week(if you have the time still) because although the questions are tough, you will get a feeling of what it is to be time squeezed and the importance of skipping a question if you can't answer it. Time management is crucial and the challenges will help you with that.

Thanks Paul, So the person's username is AkamaiBrah and he used to post the problems. No wonder I couldn't search out anything. :-D

Well anyway, does anyone have any comment on  Kaplan 800 VS Kaplan GRE&GMAT Math  ? Because I ordered the math online but I wonder if Kaplan 800 is the same or different (harder). I am talking only about the math part here.
