Best GMAT experts to follow? Materials for foundations of quant?

Hi sgiraldo2016,

You can try out the MGMAT guides as they are phenomenal and cover the entire syllabus really well. MGMAT. MGMAT's Foundation of GMAT Math guide is very helpful to brush up your basics. I must add that if you are particularly looking to discover and improve on your weak areas in Quant; a subscription to GMATCLUB tests is the best way to do that. They are indeed phenomenal and will not only pinpoint your weak areas but also help you improve on them.

Further taking multiple mocks might help. Apart from the GMATPREP, Manhattan GMAT tests and Veritas Prep Tests in my experience have good verbal and Quant section and will certainly help you point out and improve your weak areas.

Further another advantage of taking many mocks is to build up your stamina. Apart from the GMATPREP tests, taking practise tests of any major GMATPREP company ought to do that.

Lastly I would also encourage you to purchase the latest version of OG and the verbal review for some great additional practice. Here is a link that will help you with your decision.

Hope this helps. All the best.

I would also recommend abhimahna post on who to follow https://bit.ly/2Eowkps

and the GMAT Wednesday series with GMAT Ninja. He just did a video that gives a great outline to what to go through in 4 differnt stages. https://gmatclub.com/forum/gmat-ninja-wednesdays-live-on-youtube-series-2-starts-feb-259122.html#p2015584

I literally have been going through these two links all morning and I am finding some great materials and suggestions to start prepping again for the GMAT

Bunuel, obviously

I suggest you pay special attention to inequalities and absolute inequalities as these take a while to get your head around if you're not used to them. You may need extra practise as they seem to be popping up quite a bit recently in the 50/51 level DS questions and they're not that well covered in most books.

You need to get into good habits for DS from the very start. For all DS questions involving unknown variables, remember the 4 horsemen of DS which are
- the variable(s) could be negative
- the variable(s) could be zero
- the variable(s) could be non-integer
- the variable(s) could be the same

You need to consider all 4 options every time you do a DS question involving unknown variables. No exceptions. It must become second nature. You can NEVER assume that variables are positive, non zero, integer or different! Don't throw away questions because you forgot that a variable could be zero

You should also examine each DS question to determine whether you're being asked for a single discreet value (e.g. "what is the value of x?), a compound value ("what is the value of a+b?") or a yes/no question ("is x more than 10?")

For compound values, decide whether you need to know the exact values of a and b, the combined value OR how just they relate to each other (e.g if the question asks "is the product of a and b negative?", you don't necessarily need to know individually the status of a and b. If you can determine a and b always have opposive signs, or that a and b always have the same sign, then the actual individual signs of a and b don't matter)

For yes/no questions, remember that you often do not need to know the exact value of a variable. Don't fall into the C trap for these questions

Experts for Quant : Bunuel, VeritasPrepKarishma, EgmatQuantExpert, JeffTargetTestprep, GMATprepnow

Experts for Verbal: GMATNinja, sayantanc2k, Ajitesharun, mikemcgarry, daagh

Manhattanprep and Veritasprep guides are good for fundamentals.

I would humbly (but not too humbly...I've worked hard for my and my students' GMAT scores over the last 16 years) add myself to the list of Verbal and Quant experts here on GMAT Club. You can see my verified scores on the left of my profile (green checkmarks).

I would also nominate MartyMurray, who has the only verified perfect 800 composite score on GMAT Club, as well as dabral, Bunuel, HerrGrau, and AjiteshArun (verified GMAT 780 from the year 2012). Basically, anyone who can prove a GMAT score of 750 or above is a genius-level test taker.

As for teaching/tutoring/coaching ability, well, that's another matter altogether, but it is of course highly correlated to years and--more importantly--hours of GMAT prep experience.
