CT-5 considered to be the most horrifying paper in the CT series among the students is actually heart of Actuarial Science. This subject trains you for the calculation of premium of an insurance policy, the most important work for actuaries. Also you will learn to test the profitability of policy for the company. Its knowledge will also enable you to have an idea about how much should the reserves be set aside for the unit linked policies etc. After all this knowledge you can be a pricing actuary.
It is recommended that this paper should be taken after all the other papers of the CT series, but I personally feel that you can go for this paper after CT-1 and CT-4. CT-1 will give you the knowledge of the annuity functions which is the base for CT-5 while CT-4 will help you in constructing models.
I have just finished the study material of CT-5 and let me tell you I have not studied CT-4 and with a little extra efforts I was able to get that brain storming concepts. The topic which I like the most is the profit testing of unit linked policies.
I hope my efforts will give me the fruitful result. Exams are approaching and I wish Best of luck to every student.
