Attempting a paper is a tricky job; I will take up issues one by one:
In order at attempt the paper of any subject of CSS, you must know that there is no need of use a language that is very complex to understand. Simple language that makes sense and that can convey you thoughts is good enough for you to pass the papers with flying colors.
Planning the answers
In my opinion, it is a good idea to plan the question before hand. It gives us an edge over other. You can spend in this planning for sometime and then start attempting the question. The planning of answer is same as you are planning your essays; the only difference is that the answers to questions will be shorter as compared to Essay.
Can we use markers?
Yes markers are allowed for putting heading. Apart from it, there is no restriction to not to use ball pen but in my view, fountain pen sheds a positive impact. You can always use markers and pointer pens for heading and sub-heading.
What is the role of time management?
The proper time management is the key to success that’s why I put emphasis on planning ahead. You must atleast give 15 minutes to each question when your paper asks you to attempt 5 question in 3 hours.
What should be the length of answers?
Staying to the point is very good, unnecessary length will cause harm instead of benefit. In my view, it is good to write one page for 5 marks so if the question is of 20 marks, one can write fours pages and that is enough. This is how I see it.
