Hello Wayne, 

Yes, somewhat. 

According to SEBA's guidelines, it is mandatory to give examinee grace marks and moderation in marks will remain as per established norms in other boards, but only in instances when questions are out of syllabus, discrepancies in the electronic assessment of answer sheets, wrong usage of terminology in questions, etc. 

Also, under the above circumstances, the overall performance of students and difficulty of paper, there will be liberal checking in subjects, including mathematics and advanced mathematics. Under normal conditions, unless the examinee is failing in a particular subject where he will be provided grace marks, there wouldn't be any extended support.

I wish you best wishes. Don't worry.
