Salaam thanks for the valuable information. I want to know more about these two compulsory subjects ?

''03. Essay in Urdu/Sindhi..50 Marks
04. General Paper in Urdu/Sindh.....100 Marks''

Q1) are there any option other than Sindhi or Urdu for General Paper and Essay ? can i opt Balochi for Essay and General Paper, instead of Sindhi or Urdu?

Q2)do we need to submit an extra form for the screening test or we just have to submit the CCE form online only and they'll dispatch the admission letter/certificate for the screening test via post?
