I've been struggling a tad when reading some of the more confusing worded quant questions as it regards to when to use my combinations vs just taking the normal probability of a grouping. Does anyone have any good reference material I can leverage?
I am sorry to hear that you are struggling in PnC and Probability sections. I was in the same position some time ago and i followed the below given plan to overcome the struggle
Step 1:GMAT Club Math book
Download the GMAT Club Math book and go through the concepts related to Pnc and Probability. We need to cover the basics first.
Step 2:Quant Mega Thread -
https://gmatclub.com/forum/ultimate-gma ... 44512.htmlNavigate to Combinatorics / Counting Methods section and access all the links under this section , do not skip any link. All the sub osts under this section have valuable information.
Step 3: Practice Questions
In the same "Combinatorics / Counting Methods section" in Quant megathread , there is section for Questions that has links to important questions to practice under each section. Please try all the questions. You would have atleast 75 to 100 questions in total. It may take some time but after this exercise you will not struggle in this section.
PS:
Practice the same steps for Probability section in the Quant megathread post.
All the best for your preparation.
