Within time, my success rate for Data Sufficiency (DS) is falling down.
However, this time it wasn't because of my stubborn brains. The most of errors were coming from "careless errors". Simply said, I just didn't take enough time and concentration on the most of them.
Having a constantly beeping laptop close-by adds a huge amount of distraction to the process. While I did my best to put it as far as it's possible away from my hands, I catch myself constantly dropping a sight at the screen whenever it changes, the message comes or whatever not. It's not like I'm checking it, it just disturbs me.
Sounds are pretty disturbing, too. While I'm tolerant to the noise (we're living in Millbrae, which is actually an appendix to SFO), CalTrain and airplane noises are pretty common during the day. However, something like music or talking can really add some mess to the right order of my thinking process.
Hopefully, pretty soon I'll get myself back into the order and raise up the score. I need to find the way how to tolerate the disturbance, because, according to my experience from PMP, the examination room is not guarranteed to be noise-free and stupid-knocking-mooing-cracking-neighboor free.

GMAT DS
GMAT Data Sufficiency (DS) part is something that definitely needs your time and pre-understanding. OG has a quick intro into these types of questions, however, it wasn't something that I was able to get right away.
My first block of tests brought me to 50% of correct rate, which is extremely low.
However, taking some time and going through the answers with explanations, I was able to run next two blocks with 80% of success. While it's still far from heaven, it's way better I expected to see from the first run.
Hint: it was very helpful for me to draw an algorithm of solving these questions. There is one in the book as well, but I preferred the one I made myself. It's all about the order.
Step 1. If 1 is sufficient ? (Yes) Answers could be AD, if (No) BCE.
Step 2. If 2 is sufficient ? (Yes) Answer is D, (No) is A.
Step 3. If 1 is not sufficient, is 2 ? (Yes) Answer is B, otherwise (No) answers could be CE.
Step 4. If 1 & 2 together sufficient ? (Yes) Answer is C, if (No) is E.
This could look awkward, but it's not. I was able to save a lot of time by memorizing such a simple scheme.
