In the last 20 years, I have worked with far too many engineers that could not write a decent document to save their ass. You should be able to read, write and speak English well, including standing in front of a room full of people to give a presentation. At most organizations, the first step for any software development or IT project is a requirements document - written in English (or the appropriate local language.) If you are a great communicator, you will stand above your peers and advance in your career to work on interesting projects, lead teams and make more money.
While in college earning a degree in Computer Engineering, I was only required to take one semester of English. At the end of college my writing skills were appalling. I was forced to improve my writing on the job including writing product reviews for a magazine, requirements documents and documentation. I learned public speaking the hard way - standing in front of 20 people for two weeks training them on our company's product.
So, before you graduate, take technical writing and public speaking classes.
