Hi,
There is certainly a correlation, and that is why top companies would require high grades from top schools. However, there are certain skills required in consulting which we are unable to practice too much at school:
- Interpersonal skills (i.e. being an extraverted person, ability to get the buy-in from different audiences)
- Communication skills (i.e. being able to tell a story in a concise manner)
Best,
