Computer Science MSc Or BSc (Hons)?

Q: I need to decide what course to take but am having a hard time choosing. I already have a degree in something else and now am going to study computer science. Should I take a MSc degree - this takes about half the time of the full BSc degree, but the modules probably are not as detailed. or Should I take the BSc degree - could take over 5 years part time cause im working as well. What would you recommend?

A: The reasons why (in middle age) I choose to go and study part time for a computer science degree: 1. Learning - im intersted in learning about computer science in a structured way. 2. My current career path is leading no where so I want something to fall back on in a few years time - even running my own business possibly in the IT industry. 3. I will have time as my job is very flexible at the moment.
