Hi Mahesh,

The RRB exam will be conducted in an online format - Computer Based Test (CBT) - from 2016. It is important for candidates to get accustomed to this format well in advance before the actual examination. A good way of doing that is by taking a lot of online mock tests. These mock tests simulate the actual exam conditions as far as the pattern, standard and format of questions is concerned. Another advantage is that you can take the exam from the comfort of your home. On the other hand, the onus is on you to create an exam-like environment at your home when you are taking the mock test. Treat is as the actual examination. This will help you develop the examination temperament and get you accustomed to the online format.

Hi Snigdha,

There are 4 important things that you have to remember while practising for RRB-2016 online exam:

1. Practise a lot of questions from General Awareness and General Science
2. Solve previous years' papers
3. Cut out silly mistakes
4. Take as many mock tests as possible.

Check out the following blog to know more about the preparation strategy in detail.

The least angle is 120 degrees.
The minimum number of sides required to form a polygon is 3.
If the required polygon is of 3 sides, then the angles of the polygon will be 120, 130 and 140 as they must be in AP with common difference 10 degrees.
Sum of angles = 390 degrees.
But, a polygon of 3 sides must have sum of its angles as 180 degrees.

If the required polygon is of 4 sides, then the angles will be 120, 130, 140 and 150 degrees.
Sum of angles = 540 degrees.
But, a polygon of 4 sides must have sum of its angles 360 degrees.

If the required polygon is of 5 sides, then the angles will be 120, 130, 140, 150 and 160 degrees.
Sum of angles = 700 degrees.
But, a polygon of 5 sides must have sum of its angles 540 degrees.

If the required polygon is of 6 sides, then the angles will be 120, 130, 140, 150, 160 and 170 degrees.
Sum of angles = 870 degrees.
But, a polygon of 6 sides must have sum of its angles 720 degrees.

The polygon cannot be of 7 sides because that will mean one angle must be 180 degrees which is not possible.

Hence, there is no such polygon with the required constraints.

RRB is conducting a computerized common entrance test this year for their 21 boards of which Secunderabad is one. The first step is to read through the RRB 2016 notification. You can download it here: https://cracku.in/railways/info
Solving previous years RRB question papers, Practising questions from General Awareness and General Science and attempting mock tests can go a long way in succeeding in the exam. This has been explained in greater detail in Cracku blog here: https://cracku.in/blog/how-to-practice-for-rrb-online-exam-2016/

Hi Amaresh,

Questions on Numerical Reasoning mainly consist of Number Series. For this, you have to practise a lot. The points to keep in mind are:

1. Many series questions are based on differences between successive terms. That should be your first line of attack.
2. If you get Alphabet series questions, try to convert them into number series questions and then solve.

Not too many questions are asked on Numerical Computing. So, don't worry too much about it.

Hi Arif,

Questions on Calendars are frequently asked in RRB exam. Generally, questions are asked on finding the day of the week given the exact date. For example, "If 4th March 2016 is a Sunday, what day is 15th April 2018?" To answer questions like these, one should keep a couple of points in mind -

1. If today is X, 7 days from today will also be X. Similarly, 14 days from today will also be X. In other words, all the days that are 7k days, where k is an integer, from today will be X.
2. Leap year rules : If a year is not divisible by 4 and is not a century, then it is a Leap year. Also, every century that is divisible by 400 is a Leap year. For example: 1896 is a leap year but 1900 is not a leap year.

In general, if a particular date in year Y is Sunday, then that date in the year Y+1 will be a Monday, unless it is a leap year. If it is a leap year, then that date will be a Tuesday.

Many students tend to prepare for this section by going through all the different sources available on the Internet or in print. This is a very ineffective way of preparing as far as SSC exam is concerned. A good way to go about the preparation is to first make a judicious selection of about 4 trusted sources – 2 each for Static GA and Dynamic GA and stick to them. The advantage with this mode of preparation is that the sources keep updating themselves and the student need not bother about whether the answers to the questions are correct or not. After going through the information/quiz in the source, the student should make a note of the important points. These have to be visited after a week. A few weeks of preparation in this way is guaranteed to produce tremendous results.
