<p>I don’t know what the percentages are, but it is not hard at all to get into a top grad school in math, science, or engineering from MIT. The grad schools are not GPA-focused, and they know that MIT is harder than the top ivies to get a high GPA. </p>
<h1>1) If you get a 4.3/5.0 in engineering in chem E or EECS, you automatically get into the master’s program.</h1>
<h1>2) There is no taboo in engineering against going to the same grad school as undergrad, so MIT undergrads have an advantage in getting into PhD programs because they can get work in the group of an MIT prof and get a recommendation from that professor. Recs from MIT profs are more effective than ones from other schools in MIT admissions; the profs themselves may sit on the admissions committee after all.</h1>
<h1>3) My guess is that if you have a 4.3/5.0 from MIT and spend a summer doing research, you will get into at least a few of the top 5 programs in science (and maybe better than a few.) You’ve still got a shot with a 4.0/5.0.</h1>
