Hi Stacey,
As discussed I appeared for the Free Manhattan CAT taking this as a diagnostic test. This was taken without any prep whatsoever and just going through the format/content of the GMAT. Appeared for the test without including the IR section. Scored a dismal 550 (45 %tile) with Quant score as Q39 (43 %tile) and Verbal score as V28 (51 %tile).
I have tried to break down and organise the data in the format suggested in your article on analysing practice CATs following it up with my findings/analysis.
Here is my Data for Quant: 19 correct, 17 incorrect, 1 Unattempted (Last Question – ran out of time)
Questions breakup is as follows:
300-500 – 1 Q - Correct
500-600 – 15 Q – 9 Correct
600-700 – 19Q – 8 Correct
700-800 – 2 Q – 1 correct
Overall I guessed on 7 Questions out of which 1 was still a little bit estimated others were blind guesses: The topic-wise breakup of these questions along with their Q no. are as follows:
Statistics – 1 Question (# 1)
Overlapping Sets – 2 questions (#7, #14)
Extra Problem Types – 1 Question (#9)
Polygons (Circles & Cylinders) – 1 Question (#18)
Percents – 1 Question (#19)
Rates & Work – 1 Question (#35)
Maximum got 2 wrong in a row 4 times (most were 600-700)
Took more than 3mins on 7 questions out of which 2 were correct
Total time spent was 29 mins 27 seconds on these
3 questions taking 4+ mins in 30-37 (2 were from rates and work one from fractions (got confused for some time then finally did that)
Did 7 questions in less than 1 min out of which 4 were right
Less than 50% accuracy on geometry and word problems
Algebra (49 secs difference between right and wrong answers)
Word Problems (41 secs difference between right and wrong answers)
Fractions (48 secs difference between right and wrong answers)
PS Overall accuracy 64%
Level (600-700) – 36%
DS Overall accuracy – 33%
Level (500-600) – 17%
Level (700-800) – 0%
Average Time Discrepancy
PS
(300-500) – Average Time is just 13 secs correct
(600-700) – Avg time Correct questions was 3:24 secs and wrong were 2:49 secs a bit high
DS
500-600 – 52 secs for correct responses
700-800 - 4min 17 secs for incorrect responses
Right vs wrong Ques
PS
600—700 - Discrepancy is 35 secs with right answers taking more time
DS
500-600 - Discrepancy is 35 secs with wrong answers taking more time

Analysis - I believe I am exceeding time limit on the 600-700 level questions even for correct responses some of them were a bit calculation intensive based on percents and proportions over which I took a bit more time to figure out the correct approach with regard to the steps though I had an idea that they could be done correctly
- At present I believe the 2 question on 700-800 level were quite tough for me as far as taking the right approach was concerned though 1 of the questions was of exponents dealing with prime powers but since that was the second question only so I perhaps got a bit unsettled even after exceeding time limit I thought probably I could have done since I am comparatively comfortable dealing with exponents. Other Question dealt with cylinders and circles wherein I could not figure out the approach. I also believe that I am not that strong in solids/mensuration wherein I can only attempt basic questions and perhaps not those wherein there is a bit of tweaking.
- Few questions I got correct wherein I really exceeded time limit to even 6 mins on 1 question and 2.5 to 4 mins on some others. I felt I took a bit more time in figuring out the approach to do the questions which actually ended up taking more time. E.g. such as rates & work and fractions
- I feel I am fairly good in numbers and even algebra though this time I got only 50% accuracy in algebra probably messed up in DS. I believe I can attempt DS in lesser time however it impacts my accuracy even though I believe I am selecting the right answer. It might have happened since these questions are more approachable and do not really require too many steps to complete if one clearly analyses the options and so there is greater chance of committing an error.
- As far as the timing was concerned I was keeping an eye over the Question number with the approach that the time elapsed should be roughly twice of the Question number though I still think I need to attack the questions I can approach in lesser time.
- The area Sets can get a bit uncomfortable for me if the questions are lengthy or been made a bit complex. I have approach sets with the technique of taking variables for all combinations however if pressed for time I can mess it up. Same is the case with geometry which I find a bit monotonous as compared to numbers/algebra/arithmetic and my first instinct would probably to avoid the questions if I do not get it soon and would perhaps not like to delve deep and find out the right approach when it comes to topics such as sets and geometry (I feel I can still approach lines and angles without much thought). Also in algebra I think I forgot some basic principles of inequality due to which I messed up a simple question on DS.
- Made a careless mistake on statistics question on mean since I followed the approach of calculating and going the conventional manner in that process initially later on when I got an easier and logical way to approach it I made a silly mistake in that.
- Another point I noticed is that when a question becomes lengthy or has some complex variables I get a bit nervous while approaching it even though in general I might be comfortable in that area as I observed in some questions even in algebra/arithmetic. I tend to feel the pressure of time and perhaps at times would not properly read the question clearly even though I could have attempted it.
- In general I feel if I can brush up on certain topics with respect to their concepts and then practice more on areas such as algebra/numbers/arithmetic I can build up on my strengths and get higher accuracy on these hopefully with less time. Word problems specially need one to read and understand the question completely since they can be also made lengthy enough to add to the ambiguity.
Data for Verbal- 22 correct, 19 incorrect (Attempted all finished 3 min 12 secs before time)
- Did not really blindly guess on questions
- There were 4 Questions wrong in a row (16-19) out of these first two were (600-700) level and other two were 500-600 level. Took 3:25 secs for the 16th Ques which was an RC question type.
- There was just 1 question on SC (Concision, Meaning, Idioms) wherein I exceeded the limit of 2 min by 18 secs and got it right though.
- There were 7 Questions in RC on which I exceeded the limit and total time spent on these were 23 min 12 secs. I got 4 correct. There were 3 questions on specific detail and 2 on main idea.
- When it comes to questions which were too fast and were incorrect the following were the numbers:
a) SC – 1 Question
b) CR – 6 Questions
c) RC – 1 Question
- Now coming to the accuracy part of the questions overall I got 43% accuracy in CR did not get any 700-800 Question correct and low accuracy on 500-600 (40%)
- In SC only the 600-700 level questions had accuracy of 40% overall it was 60%
- There was average timing discrepancy in the following areas:
a) CR – 300-500, 600-700
b) RC – 500-600
c) SC- 300-500, 600-700
- The timing discrepancy in corr vs incorrect questions were as follows:
a) CR – 300-500, 600-700 (Wrong ques took lesser time)
b) RC – 600-700 (Wrong ques took lesser time)
- Now the content category data is as follows:
a) CR (Overall accuracy 43%):
Category 1 – weaken argument, draw a conclusion, explain discrepancy, provide example
Category 2 – Find assumption, evaluate argument, strengthen argument, restate conclusion
b) RC (Overall accuracy 58%):
Category 1: Passage Structure
Category 3 : Main Idea
Category 4: Specific Detail
Category 5: Inference
c) SC (Overall accuracy 60%):
Category 1: Pronouns, Meaning, Parallelism, comparisons, quantity, connecting punc, concision
Category 2: Modifiers
Category 3: Verbs
ANALYSISHere are my observations which are on a high level and probably not specific enough based on sub areas/content types since I would be more aware of these when I will be going through the study material:
- I believe CR is my weakest point out of all the three sections which I have noticed in general as well. While going through the questions in CAT I was able to single out a response however it seems there is an inability to see through the subtlety and probably there is a need to build the fundamentals. I can observe that when it comes to evaluating arguments I tend to make mistakes (assumptions, strengthening/weakening/conclusions). It happens that out of 5 options I can narrow down to 2 but the 2 options have different interpretations of virtually the same answer and there it is I get confused and probably select the wrong answer based on my instinct and understanding and this is what happens in most of these question types. So perhaps there is a need to thoroughly understand the argument and see through the subtlety in order to clearly differentiate between the answer responses
- I believe I have a fair grasp of grammar though I am not sure how it is going to be on GMAT which is based on American style and usage. SC is perhaps my strongest area out of all the three testing areas. I would generally be able to attempt them in a short time however there are instances where I instinctively select the answers and end up making mistakes even though I think I might be correct i.e. These mistakes would not necessarily be silly/forced but based on my instinct. That can be a threat since I wouldn’t know that I am going wrong.
- In RCs I tend to take a bit more time than usual and may rush into things under pressure. At times I might just skim through the passage and would overlook the main idea. Otherwise when I am properly reading a passage I still think about the time factor and get nervous. Though I believe I can attain higher accuracy if I completely read the passage and comprehend it. I tend to get confused in inference/main idea based questions wherein there is a lot of subtlety and one really needs to grasp the passage. I feel at times I probably think too much on certain questions and just infer an answer as probably I believe the passage is hinting towards a response which is at a deeper level though I do this only for certain questions mostly inference based and end up making a mistake along with taking up too much time. Overall I believe there is an inconsistency in RCs and as pointed above similar to SCs I might not know that I am going wrong. At times I may get the purpose/tone of the passage and then on other questions I truly misinterpret and get confused between 2-3 options.
This was my analysis based on my observations and the data too. I would like to also add that I have a basic aptitude for both verbal and quant and have been regularly cracking aptitude tests conducted by companies during the interview processes though obviously the GMAT is quite different in terms of the course as well as the format/difficulty level. Though I have appeared for some domestic competitive exams conducted for getting into a post graduate program but I did not fair really well on those even though I thought I had done reasonably well on my attempt. Obviously they were not adaptive and focused on accuracy and speed. Now I am looking to score high near about 730-740 so I clearly need 170-180 points jump. Kindly let me know your feedback for the above analysis and then I will post my rough study plan to seek your advice.
