Hello All,

I am posting the pattern and some of the questions(memory based as we have to return the q-paper) that were asked in the BEL exam-4th July,2010. I am from computer science field.

There were 4 sets. My set was A.

Pattern: 150 objective type questions(only 1 correct option)

2.5 hours time limit

1 mark for each, 0.25 negative marking

Questions were:

1. 1 English passage (level-easy) followed by 5 ques based on the content.

2. 3 vocab based ques in the form of idiom/phrases.

3. A data table followed by 10 ques(calculation intensive). Each que had two statements. The options were:

a) mark 1 if only (i) is correct

b) mark 2 if only (ii) is correct

c) mark 3 if both are correct

d) mark 4 if both are wrong

all the 10 questions required to calculate percentage increase or decrease in the values and then mark any of the option according to the result.

4. 5 questions- sequence based

5. 5 questions on a set. easy level

The above 28 qs were aptitude and English based, rest 122 were technical-both computer science and electronics based. Some of them:

1. The order of binary search algorithm?

2. The algorithm used in quick sort?

3. which is not an example of network layer?
