paper change

hello
i attempted p5 for the first time and got 49..
i will be re attempting p5 in march
bt i just want to know.. should i change the paper to p4? i had enjoyed f9 and passed in first attempt and that time i had used opentuition videos.
i am having a slight confusion..
because people get stuck with p5 for a long time.. and to be really honest for p5 i had taken classes from an excellent tutor .. who had told me how to answer and did past papers and i he todl me students make these mistakes so dnt make them.. so i had kept all that in mind.. and..the exam was defntly hard bt there wer some easy questions.. i remmber feeling happy that ok i will pass.. i was reallynshocked to see a fail.. so.. basically.. i want to give it another attempt but i am scared deep down like.. will i be wasting time.. should i do another paper.. because many people had told me not to take p5.. but i ignored all that took it.. so.. what should i do now.. should i take p4. all the papers of acca.. so far .. i had done.self study.. and i had a method of studying.. watching lectures and doing the kit 2 times.. that has helped me.gt through.. but fr p5.i took extra help just to b on the safe side.. now i feel extrmli terrible.. what if i made a mistake.. should i hav takem p4.. or should i stick with p5..
