Haha, my subjects for AS are :
Mathematics - Reason : I just LOVE math
Physics - Reason : It's my best science.
Economics - Reason : Planning to do Actuarial Science. Would need it.
Thinking Skills - Reason : It's compulsory in my college for AS -_- but it helps to develop my mind.
For A2, it's the same as the above without Thinking Skills but with Further Mathematics. And why I wanna take Further Math? I LOVE math
Besides, it's more challenging and I learn more that way
Oh By the way, it's all Cambridge A Level xD
