Roster can not hold more than 30 questions

My questionnaire has more than 30 child questions in a given roster.While I was compiling it flags error message"A roster can not hold more than 30 child questions". What if I split the roster into two?
Thank you,

Dear Wondu,

Yes, it is better to split your roster into 2.
Also you can read about the limits our system has:
