Hi guys, gals,
I've been working hard to get through the first part of my prep, the OG11
for my coming first attempt at the GMAT come 1 Nov 06.
After reading the posts (thanks to all, great stuff!) I realised that a good detailed analysis of my errors through the error log
would help me in determining where my attention should be focused on.
Not having a huge idea what an error log
should look like, I worked on a few versions off excel. It would be great if anybody could give some feedback on how i can improve on my error log
I essentially broke down the questions in each segment (CR,RC, PS,etc.) and made a numbered list of the sample questions from OG11
, and whether I got that questions CORRECT or WRONG. Focusing on the wrong questions, I allocated a REASON for the error. And further on, I categorised the questions according to the classifications given in OG11
. I also timed myself when attempting groups of questions, and logged it down.
I was then able to calculate, aboslute and percentage scores, as well as identify primary reasons for errors, and categories and sub-categories that caused me the greatest grief. I also calcuated average time spent per question.
I am wondering if this is what many of you meant by an error log
? Well, what I've worked out so far has helped me realise some stuff.
Here is the data that I have collected so far:
Quant: Data Sufficiency
Total No. of Qn: 155
Correct: 118 = 76.1%
Wrong: 37 = 23.9%
Wrong Technique = 51.4%
Careless Method = 24.3%
Wrong Data Interpretation=16.2%
Reading Question Wrongly = 8.1%
Clueless = 0%
Categories of Errors
Arithmetic = 54.1%
Geometry = 13.5%
Sub-Categories of Errors
Properties of Numbers = 25.7%
Arithmetic Operations = 20%
Inequalities = 17.1%
I also did a quick analysis of the last 30 questions of each section as I figured that these were typically the harder questions out of the lot. I realised that my average score dropped a little if I were to analyse the average grade of a smaller sample set of 30 questions.
But not to bore you guys with details, my quant and verbal sections all average a low 80+% CORRECT. Zooming in to the last 30, it went down to mid to high 70+%.
Biggest hit was in Quant- DS Section. 76.1% total average dropped to 63.3% for the final 30... eek!
Using these data sets is helping me find my weak points. But do you guys think that my analysis is not robust? One of the problems I realise is that I should also include DIFFICULTIES in certain categories in which the questions I answered correctly. But I find it hard to include it, because the list just gets very long... I even initally included CONFIDENCE LEVELS in my list of attributes (such as ABSOLUTELY CONFIDENT, and WILD GUESS!). With that I forsee that I can even analyse my hit rates when I guess wildly, or how often my gut feel of confidence is actually wrong!
But i thought that was just a little too much definition for one person's set of data (and what more only over 1 month of prep).
Getting close, and I'm getting nervous too ... so any feedback, please, I'd be so grateful!!!
