I am a senior computer engineering major at a university in the US. My overall GPA is 3.4 and my major GPA is 3.85. I've had two summer internships and one 6 month co-op. I'll be going to the workforce as engineer to one of the companies that I've worked for right after graduation. After that, in one year, I plan to apply to an Ivy League school for admission into their MS in Electrical Engineering program. Given that I do well with GRE, have strong recommendations, etc... which will look better: 1) If I focus on my last semester on bringing my grade up to 3.45-3.49? 2) Continue on with my co-op work experience this Spring as a part-timer and only graduate with a GPA of 3.4-3.45? Note, the GPA I mentioned above are calculated to what I can get at most.
