One of the challenges students faced after completing their secondary school studies is to decide on which course to pursue next for their undergraduate studies. The same problem is faced by Siti who has a hard time deciding on whether to study Biology, Chemistry or Computer Science. Personally, Siti likes reading, maths, logic as well as programming. Based on her research, she found that those who wants to study Biology, needs to like reading and doing experiments while those who wants to study Chemistry needs to like math and doing experiments. As for Computer Science, they need to like problem solving and programming. It is known that to like problem solving, you need to like logic and maths. It is also known that to like doing experiments, you need be adventurous and analytical.
