This question has been cropping up in my mind for years, I guess now is now for me to speak up.

I'm a final year student of Agricultural Engineering in one of Nigeria's universities. The thing is, I don't really like this course I'm studying, not that I hate it, but I don't see myself doing something with it after school, I am doing well in school I must stress it. I'm more of a tech person and I love anything tech so much (I do everything programming and more), may be Computer or Electrical Engineering could have somehow matched my interest. The deal now is that I want to go for my Msc immediately after my B.Eng but I want to switch to a field which really cooperates with my passion.

My question is, being a graduate of Agricultural Engineering, does it work easily if I say I want to go for another course with my MSc? Mind you, I will graduate with nothing less than 4.0/5.0 grading system and I will like to further abroad, I know about IELTS exams for postgraduate studies and all.

Please if you have vast knowledge or experience about all I have lined out, I need you to feed me from the richness of your knowledge. Thanks in advance.
