i think you shall take english because it is the trade and the busness language
you should decide first what field do u wanna work in then after that search for the courses that are related to this field and apply for them.. for example if you are willing to work in the admin department u have to take communication skills, presentation skills... etc
English and computer skills are essencial basics for any job, other than that you need to know first what you wanna be, which job you wanna have sales, marketing, hr, customer care, etc., then choose the courses that increases your knowledage in that feild, and my advice is not to rely on courses only, but you have the ultimate source of knowledage in your hands, the internet, do researches, read articals.
Good Luck
i think that is based on your targeted feild
