1)Transcripts show your overall class rank - whether you like it or not. If you are a top student, it is great. If you are average or below (50% of the students obviously have to be below the 50-percentile) it is not so good - something to keep in mind.
2)If you repeat a course to improve your grade, they will show both grades - but will happily collect your tuition fees twice.
3)Transcripts show courses in Chronological order and contain abbreviations. It is a jigsaw puzzle some employers may not like to navigate.
