So put this into full perspective. It's not that you got 50% correct. You had 12 + 11 = 23 problems, and you answered 6/23 correct
I never thought about it, Can't believe that if I guessed, I could have got the same accuracy. This certainly gives me a strong reason to stop spending time on tough questions. Such an "Aha" moment!!!
Here is my full analysis and answers to each of your questions.
1. Reason my score dropped: a. I think that the primary reason is mismanaged timing in the real test. I finished my last MGMAT just on time but there was an up and down timing issue. Also, Stamina might be an issue as I felt a mental block on few questions towards the end of verbal section.
b. I feel another difference in real GMAT was that after my quant section I came back and went to my seat but still there were 3 min left for my break. But I had to start my section as per the test center instructions. Though, I am skeptical that this could be the reason for such a big drop.
2. How do I need to change my approach after reading the articles you suggested.a. Decision Making: I am not making the correct decisions. I should know when I need to bail out and when I should spend some more time to get this question right. I have that "But" feeling while doing some questions due to which I take more time on those.
b. One Min Sense: I think I need to develop the one min sense, which I think I have developed after giving so many practice CATs but still have to get better at it. Sometimes I just cant get stop solving the question and change my strategy. I believe I need to consciously make this decision as I cross the time limit for a question.
c. Careless mistakes: I noticed a pattern for few questions I solve. In quant, I do the math, solve the question but I none of the ans choice is that answer. Then I re do it to see that I made a careless mistake in some calculation. So, I need to stop making these careless mistakes.
3. My buckets DiscussionI did my last MGMAT in depth analysis. I gave another practice CAT recently to check my current level and analyse my strengths and weaknesses.
I also took the GMAT Focus test for Quant. I saw some really tough questions on the test, but this time I changed my strategy to educated guessing as soon as I understood that I can’t solve this question in 2.5 – 3 min. I got 20 correct and 4 wrong and a scaled score of 47-51 with 80% Confidence level. (I have been working on few topics of my prioritize list before this test)
GMAT Focus Analysis:
4 incorrect, 1 question correct with 3 min 44 sec time spent:
1 correct: 700 level Word Problem: I spent 3 min 44 sec on this tough word problem DS question. I time I took was to read and comprehend the question
4 Incorrect:
Word Problem with Statistics (Mean) (700 level) – Did a calculation silly mistake
Tough Probability question: I figured out the strategy to solve correctly but it took me a long time so I bailed out.
Silly mistake on word problem with linear equations (700 level)
Weighted average question: I made a mistake while calculating the average for a mixture.
Below is my Tests analysis:
QUANT:
Broadly, I am better at DS than PS, but looking at the timings, I see that even on 750 level PS problems I spend less time. The reason is that I either make calculation mistakes/guesses while at the end of section or I have content problems. I have taken note of them in below buckets.
Strengths:
a. Exponents, Linear Equations – I get the 80% of the 750 level questions right within 2 min
b. Number Properties: Probability & Combinatorics – 600 – 700 level questions
c. Algebra
d. Quadratic equations
e. Inequalities – 600 – 700 level
f. FDPs: 600-700 level
Prioritize:
a. Divisibility and Primes: I am getting these questions consistently wrong in 2 min. The reason is I am not taking the right approach to solve these questions.
b. Inequalities: Getting wrong due to incorrect strategy. For example, picking numbers or use algebra
c. Number Properties – (perfect squares) – I forgot the concept
d. Consecutive integers: Getting wrong in 3 min time. Again I think I am applying wrong strategies
e. Digits and decimals: I am making mistakes due to holes in foundation and wrong strategy.
f. Modulus questions: Making mistakes due to holes in foundation. I revised the concept and did few tough questions on this. Saw the results in GMATFocus
g. Rates and Work: On 700-800 level questions I make mistakes in the content.
Ugh:
a. Geometry (Triangles / Circles and Cylinders) : Just could not figure out how to solve the questions. On many questions, I kept staring at the screen thinking.
b. Exponents and Roots: 750 level questions getting wrong in crazy slow time
c. Percent’s and mixtures: Content Issue
d. Statistics and medians: Content issue
e. Divisibility and Primes: 750 level questions
f. Rates and Work: 750 level questions
The above Ugh list mistakes I make due to tough questions and thinking about the strategy to solve them

Weaken the Argument: consistently getting them wrong. Reasons: Picked incorrect choice which did not have relation with the argument, questions involving math
Strengthen the Argument: Getting questions wrong due to forgetting what I am looking for while reviewing the ans choices
SC:
Long sentences: I get them right but it takes 3 min. comprehending the Sentence takes time
Modifiers: Tough modifier questions getting wrong due to not paying attention to the meaning
Meaning errors: Consistently making mistakes on SC questions by not paying attention to the meaning of the sentence
RC:
Inference questions
Ugh:
Must be True /Inference CR Questions: I just take a long time to solve them. Specifically those which involve Math in the question
Assumptions: 700 level questions. I take a long time to solve it. It also involved math
Inference RC Questions – 750 level
Weaken the argument = 750 level
Finally, I have 2 more questions:
1. In my recent practice CATs I follow the strategy of Time Buckets. Now, if I am ahead of time in one bucket, then I tend to spend close to 4 min on a question (thinking I still have time in this bucket). So, what should I do if I an ahead of time by around 3 min in a bucket? Should I spend more time on a tough question or bail out by 2 min?
2. I have used all my practice CATs. I tried resetting the MGMATs, but I see repeat questions which I still remember. So, any suggestions on how to do further pratice?
Thanks for all your help
