You must know that there is a rating system to assess bilingualism. Level A indicates a beginner’s level. Level B indicates an intermediary level and level C indicates an advanced level. Generally, C-B-C is required for the highest level; the first C is for an advanced oral level, the B is for an acceptable writing level, and the second C is for someone who is able to read with no problem.

If you were to use that rating system, there would be more guarantees. We would have our cake and be able to eat it too.
