A better overall score improves a candidate’s chances for immigration. That much is simple – yet, the misunderstood word here is overall. If you are confident in one or more of the abilities tested, you may be inclined to dwell more on that skill. By neglecting your weaknesses and overperforming in one category, the candidate may get a good average score. However, the Comprehensive Ranking System (CRS) rewards each ability separately. This is why some candidates find themselves repeating exams and doubling preparation time, without improving their overall CRS score.
