MOSCOW David Robinson Spurs Jersey , Jan. 30 (Xinhua) -- Russian special services had identified the terrorists involved in recent twin suicide attacks in the southern city of Volgograd, the National Anti-terror Committee (NAC) said Thursday.

"The identities of the two suicide bombers were established shortly after the explosions. Asker Samedov and Suleiman Magomedov were members of the so-called Buinaksk terrorist group. Their names were not disclosed earlier for security reasons," the NAC said in a statement on its website.

Law enforcement agencies had also detained two men suspected of being accomplices in last month's attacks, the NAC said.

Two brothers, Magomednabi and Tagir Batirovs, who allegedly helped transport the suicide bombers to Volgograd, were detained Wednesday as a result of search operations in the southern republic of Dagestan, it said.

Operations were continuing to identify and track down other accomplices, including the masterminds of the attacks, the committee said.

The twin bombings killed 34 people and injured more than 100.

Q. What was the change in your prep strategy during last 30 days to CAT?
My preparation stage lasted from August to October. In the last month, that is October I made it a point to revise each and every concept studied for last 2 months. The strategy was to strengthen topics which I already knew and not be worried about questions which I didn't know to solve.

Q. Did you expect to get this much percentile after your CAT? How did you evaluate yourself on the basis of your mock test scores before CAT?
Frankly speaking, this was the last time (4th time) I was writing CAT. I had given around 30 mocks which I did carefully analyze. However, I never hit a 99 in any of my mocks. The pressure was on me since I had quit my job to take a break and prepare whole-heartedly for CAT. I made it a point; I wouldn't do random guessing for the mocks. I benchmarked myself on the different sections. I build on my strength areas and stayed confident with that.

Q. How did you prepare yourself a day before the D-day (your CAT Test day)?
I started relaxing 4-5 days before the exam. A day before the D-Day I went onto watch a movie met some friends and put myself to sleep quite early. I also made sure the food that I ate was right, because I didn't have home food as I was staying away from home to write the exam. Read More

Q. What was your question solving strategy on the CAT testing day?
I had made a mental note to myself that I am not going to fall in love with a question. Strict 1.5 minutes for each question. If I wasn't sure of an answer, I skipped it. It was very important considering the crucial time limit of the exam.

Q. What was the toughest & easiest section for you in CAT? What was your strategy to handle the difficult part?
I clearly remember Verbal and DI section used to haunt me a bit, especially the grammar questions and certain parajumbles, reasoning questions. Quantitative sections in some mocks were very tough as well. The key for Verbal and DI section was to handle DI questions first, crack some of them, build some confidence and then move onto the Verbal questions.

Q. One preparation area which influenced your selection to this Top B-school heavily. How?
One critical area that you should know inside out is the work you did and most of the times the ultimate reason why you want to do an MBA. This is easier said than done but interviewers would like to hear from you that answer. I felt in most of my interviews I did that part well. Read More

Q. Your long-term preparation strategy for GDPI
I was up to date with most of the current affairs. THE HINDU newspaper did help me a lot, especially the Editorial and Opinion page. More than building vocabulary, I got to know different perspectives regarding the same issues. The Economist is another magazine that you can read for different perspectives. Nowadays, the stress on WAT is there. Make sure, you can structure your thoughts about an article and pen it down. That is quite crucial in scoring marks for WAT.Read More

Q. What was your biggest mistake during selection process beginning with CAT
My biggest mistake came in the form of not preparing for GD PI mainly because I resumed by job in the industry after writing CAT. I had no formal coaching. In fact I was teaching CAT students as well for some time in my hometown, Trivandrum. That was one of the best sources of revising since you have to know your concepts deeply to teach students. So, the depth of studying was larger.

Q. Your advice for CAT 2014 Aspirants
I have a smile when I write this. Umpteen posts in various forums; I realized that the best advice is to l.
