Should I need to enroll in MS Computer Sciences to boost my career as a marketer + web developer (I already done MBA).

Welcome to Fluther.

At this point in your career I want to suggest very politely and respectfully and sincerely that paying more attention to your English – and by that I mean a lot more – would do more for your career development and prospects than any technical instruction you might take or certification that you could attain. By all means take the computer science classes; they will surely help. But do a lot more writing to a critical audience (such as this one in Fluther, if you ask for criticism, which you have not) and you’ll gain more than you might have expected. Your writing needs work; on the basis of your writing alone I wouldn’t even consider you for employment, regardless of technical skills. I am not alone.

I am not writing a business email or sales copy here. This is just a problem that I am going to discuss with Fluther community to get some solution. I know how to write well. Anyhow thank you for your advice. It would be more helpful for me if you read the question, understand it and then focus on answering in the best way.
Thank you

I have one son with a BA in computer science and another with a P.hD. in it. They are both doing terrrifically well in their careers. I think it is acquiring the skills more than the degree per se that matters so online programming courses might be fine.

There are several places online where you can take coding courses, including the Khan Academy.
Java and C++/C# are usually used for serious apps. PERL for sys-admin work, javascript and HTML 5 for web pages.

I think you could probably just find classes to learn the specific computer sciences you want to know instead of going back for a whole othe degree unless you plan on changing careers entirely. As long as employers can see that you have those listed on a resume and you can show where you have used them on your resume, it should be enough. A lot colleges and universities will offer community education classes which aren’t usually that expensive. Some may let you take classes without enrolling in the entire program, too. I might suggest checking a community college to see what they offer. The one near me is very good for that kind of thing. Also check with your human resources department to see if they have any sort of tuition reimbursement. They might pay per class and you can save a few dollars.

It depends on whether you want to have a degree, or just to learn web development/programming. If it is the latter, I recommend looking at the many moocs out there, for example:

http://ocw.mit.edu/courses/#electrical-engineering-and-computer-science
https://www.coursera.org/course/programming2

I imagine that a computer science degree would take you 2–3 full-semester years
