Respected sir, 
     1. ) It could be more comfortable to have the options of "View Approved questions" inside the "Available questions". 
     2.) Please provide "chapter" as well the "Topic" wise.
  This will give quick summary of the questions entered Chapter/Topic wise and  the lecturer can view the questions entered in the concerned Topic/chapter.
            Thank you in advance,
Regards,
Naganjaneyulu,
Mechanical Department.
