Well, so I just took the second diagnostics test and got 750! These are the results:

This is the difference with the previous:

There are very interesting conclusions to be drawn from this.

Firstly, by no means these results ensure I will get more than or equal to 700 on the test I feel… but at least they indicate I have a true chance of getting it. So I am happy and relaxed and will go to the exam on Monday with confidence and will just try to do my best.

Then, you can see that the improvement in score is mainly due to verbal improvement. This is crazy… I am dedicating most of my time to Quant, 90% or more… and you can see how hard is to climb those last points. Clearly I am particularly good in the reasoning part, which I feel does agree with my actual situation as a person. For the math what happens is that it is easier to get perfect at it given enough skill and time… so you have many more people getting those 50,51 scores.

For me to go to that level would require too much time I guess? Because you have to basically be good at the hard bits of every topic. Hmm… In any case at this stage and with such little time the best I can do is to just keep analyzing what went wrong, why, and to improve. That’s what I will do.

I can also see that my score can realistically be between 680 – 720, and that for +720 scores I would need a tad of luck. Let’s see… I have not really analyzed the questions individually yet… so I am not sure how much luck or not there was in my current scores.

It would be so awesome if test on Monday goes well. Let’s see…

- Learned an interesting property of numbers: http://www.veritasprep.com/blog/2011/05/quarter-wit-quarter-wisdom-a-remainders-post-for-the-geek-in-you/

A question like below can be solved using it:

We know that if n = (k+1) cubed, we know that remainder of that by n will always be remainder 1 as the result at top is a multiple of k and then plus one. Anyway, this is good to know in the background, but plugging numbers might be a safer approach on test day.
