Reviews of BS in Environmental Science graduates:


About my college education:
It was a bit bland, to be frank. The degree program I chose was relatively easy. Most of my fellow students paid more attention to matters other than academics. It's not particularly difficult, but one has to stay focused on things that really matter.

Helpful skills would be good information gathering and retention skills, open-mindedness, willingness to work with others.

My current job:
University Instructor/Researcher

Am I using what I learned in college:
One skill I acquired during college that turned out to be important is the development and maintenance of social skills. It is highly necessary to maintain a certain degree of professionalism.
Although the specifics of my college classes have long since been lost, I found the general knowledge pretty useful as a backbone for further learning. Being able to speak in front of a large audience also turned out to be useful, more so because I tend to get nervous when it comes to public speaking.

How long did it take to find a job after graduation:
3 Months

Do I recommend studying BS in Environmental Science and Technology:
Employment oppurtunities include Environment-related research, Government offices, Education, Freelance writing.
