Dear student,
  Good luck for the forthcoming Annual Examination.
  To score good marks, you need to follow the following tips.
1. You need to write correct answer for the asked question instead of writing unnecessary things for example for the question What is your name? You need to write the following answers.
My name is John, or My full name is John K. Henry or Introduce more about you.But, do not write like My name is ____ (name is missing)
2. First, you need to increase quality, then quantity of quality.
3. Minimum one page answer for any of the question.
4. If, question carry 5 marks then minimum 2 pages with 2 examples.
5. If, question carry 10 marks, then minimum front/back 4 pages with examples.
6. Wherever necessary, draw figure with figure and labels.

First explain the topic.....Then write Syntax......Then write Examples.....List OPTIONS if any in Table with explanation.....Give few examples for few options......

7. Write minimum 3 examples for each UNIX command. If you do not write examples, then you loose marks.
8. Practice Shell and Perl programs from the text book of Sumitabha Das author.
9. Yes, you are intelligent, go ahead, reach your goal, "your future is bright do not spoil it" said by V.T.U.
10. Whatever you write, write neatly with correct question number.
11. Do no compare yourselves with others! instead compare yourself with your last performance!.
12. Move the examination hall with Hall Ticket, ID card, Blank ink ball pen and compass box.
13. Write your V.T.U. no. correctly on answer booklet.
