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?

8. one question to calculate determinant of a matrix
9. one ques to find rank of a matrix
10. a pointer variable can be
a) passed to a function as argument
b) changed within a function
