Answer:
Yes, it will be possible to work with such people but at the same time, it will also pose a huge challenge to work with such diverse class of people.
Step-by-step explanation:
Considering the bolded words or phrases are - "in concert with" and "all walks of life", we can safely assume that these phrases are used to signify or mean something deeper than they may seem to suggest.
First, the phrase "in concert with" means 'working together' whereas "all walks of life" means people who have different jobs and positions, literally meaning people with different characters and backgrounds.
So, coming to the answer for the question "could you work in concert with classmates from all walks of life?", I would say that it will be a challenge to try to work with people from diverse characteristics. There can be conflicting interests but at the same time, it will also pose a chance to get diverse exposure and experience with such diversity. So, I must say, for me, it will be a challenge to work with them but not impossible.
