One more thing you have to consider.

Since you are still an undergraduate without proper working experience (Full time job) and you are planning to go for post graduate degrees right after you got your undergraduate degree. It'll be very tough for you.

Like tishaban said, your EQ and IQ is very important. Juggling between your work and studies is SUPER hard. I am going through a hard time right now.

My suggestion is, after you graduate, get a full time job. Manage your job first. If and only if you have time and also the effort to pursue your studies, go for it.

No point studying half way and just quit to concentrate on your job, or the other way round.
