The University's transcript is an official document listing your complete academic record, with no alterations or erasures.
The University has a responsibility to maintain a consistent practice in order to ensure that the integrity of its reporting is not questioned.
It is not uncommon for your achievements in one program, or one year of study, to be of a lesser standard of achievement as in other parts of your records. This may be because your choice of program was inappropriate, or because external personal factors affected your academic performance.
As such extenuating factors are not explained on the transcript, it is often suggested to students that you attach a statement to the transcript explaining those aspects of your transcript that you are unhappy with. This will enable employers to make appropriate allowances when reviewing transcripts.
