The IB section of TheStudentRoom is very much dead. & IB related forums discuss specific papers hours after theyve been done (i.e. too late)

Hi, I didnt like solving paper 1 at all, for me it was considered one of the worst papers that I did. I did indeed find paper 2 a little better than math paper 1.
