The issue of CC|EC is done throughout the year. There is no such date called the last date for obtaining EC | CC. However, since the EC|CC is to be obtained to be eligible to appear for the main/final examination, care should be taken to ensure its timely receipt (i.e. within such time so as to enable you to file the application for examination in time).
Postal Coaching - Not in Receipt of CC within time
A student should have submitted all the requisite papers within the last/cut off dates.
Where a student has submitted all the required papers and is still awaiting receipt of CC, on the last date for submission of examination application, he/she may (not can) submit the examination application with the requisite fees [in spite of not being in receipt of the CC before the last date] making a mention of the same.
It is in the students own interest that he/she pursues his/her case with the respective regional council (postal coaching students) or the center where he has undergone the oral coaching (oral coaching students) and obtains the CC|EC and sends a photocopy of the same along with a letter explaining his case to the head office where the examination applications are dealt with.
This would amount to the student making a provisional application on the anticipation that his/her EC/CC would be ultimately received. If the student fails to submit his/her EC/CC within sufficient time subsequently, he/she may not be issued the hall ticket for the examination.
Submit Papers as Early as Possible
Failure to obtain the EC/CC may be on account of the reason that the student has not qualified (i.e. got the minimum required marks) in one or more papers that had already been submitted. In such a case, the student has to re-submit and qualify in that paper to be eligible for issue of CC.
That is the reason a student is required to submit the eligibility test papers as early as possible so as not to place himself/herself in situations as above.
Oral Coaching Students
Students taking up oral coaching would be issued CC by the coaching center itself. The case of not being in receipt of CC in time would be only on account of the student not qualifying in the required number of papers, in which case, the student cannot make an application for examination.
