I am planning to sit p1 p2 p3 and P4 In June 2015! P4 is an optional subject and other three are essential! One of my friends said that I won’t b able to do the optional without doing the essential ( P1, P2, P3). Is it true?? Do I have to complete the 1st three to continue with P4?? I am a full time student and I would wish to take your advices about my decision in doing four subjects in professional level! Please do reply
