Please read the instructions carefully.
INSTRUCTIONS TO CANDIDATES
Read the following instructions carefully before you answer the questions.
Answer are to be given on the answer-sheet, which combines both the tests:
1. Please write your Centre Code and Seat No. very clearly (only one digit in one block). Before writing your
Seat No. get it ascertained from the Centre Conductor. Please see that no block is left unfilled and even
zeros appearing in the Centre Code and Seat No. are correctly transferred to the appropriate blocks on the
booklet and on the answer-sheet.
Example
Centre Code.
Seat No.
For all subsequent purposes your Centre Code and Seat No. shall remain the same. Centre once allotted
will not be changed.
2. All questions carry one mark each.
3. Since all questions are compulsory do not try to read through the whole question paper before beginning
to answer it.
4. Begin with the first question and keep on trying one question after another till you finish.
5. If you do not know the answer to any question do not spend much time on it and pass on to the next one.
Time permitting you can come back to the questions which you have left in the first instance and try them
again.
6. Since the time allotted is very short you should make best use of it. The rough work is to be done in the
box given under each page.
7. Remember you have to mark on your answers in “Scholastic Aptitude Test” Section of the answer-sheet
only.
8. Answer to each question is to be indicated in the answer-sheet by encircle by black pen in the appropriate
number of alternative in the answer-sheet from amongst the ones given for the corresponding question in
the test booklet.
9. Do not write anything except Centre Code, Seat No. and rough work anywhere in this booklet.
