Consulting job is all about your luck. Some people are so lucky that they don't even need to work. They spend almost all time watching moving and reddit in work!!! May be they need to fix one bug in one week of time. but for some people its entirely different. Even thought you work hard and you work 15 hrs a day, it might not work. I have seen both kinds.
My suggestion would be if you think you have some luck, they definitely you can go for it. Also, if you are a smart person(gpa near 4.0 in any field) you can go for it. I am sure you will do lot better and you will get lot to learn too.
but if you have hard time leaning new things, then it might not be a good option. bt still you can try. you might failed many time. Morally you might feel low bt you need to hold tight. bt at the same time you would be learning too. this way is quite tough, bt at the end you would be a good IT professional.
