Obviously, CS is not an easy subject and only those with CS academic background opt for this subject. Look at the score of my fellow colleague who has decent score in CS. I believe if you have CS background, go for it. It is better and high scoring option than all other subjects in 200 category such as Accountancy & Auditing, Economics, Political Science & International Relations. The thing that matters is how you attempt it irregardless of its scoring trend in previous years, etc
