Hi, Actuarial Science is a very challenging course. I would recommend it, if you are extremely numerate and proficient in mathematics and statistics and you enjoy it a lot. If so, you should definitely give the Actuarial Common Entrance Test (ACET). It is held twice a year, usually in June and December. It will give you a feel for what lies ahead in the future. The test also acts as a filter for the institute. If you find this exam anything but a breeze, you can expect that the papers ahead will be much more difficult, and you should reconsider your prospects. If you find this pretty easy, well, good times could lay ahead. Instead of doing no graduation, I would strongly recommend doing an under-graduate degree in statistics. It will complement the actuarial Science course beautifully and symbiotically. If not statistics, you could do a degree in commerce to give you a general commerce awareness. I am sure this should be trivial to manage, as the commerce degree won't require much of your attention. This will act as a buffer, and enhance job prospects. A graduation and a reasonable number of papers cleared will lead to very good employment prospects.
