Masters or undergrad petro engr degree

<p>I need some advice. I got a bachelors in computer science in '06. Worked for a while but decided I wanted to go into P.E. Unfortunately I think I got the wrong advice to go back and do a bachelors when I could have started a masters in petro instead. I just started this semester and I'm on track to get the bachelors degree in December 2013 latest. Should I stay on this track or keep taking classes thru next semester then take the GREs and apply for the masters program starting next fall? Thanks.</p>
