<p>i went through the process last year and, while much of the above advice is good, not all of it applies perfectly to phd admissions in pure mathematics. in regard to admissions in pure math, a few (chronologically ordered) thoughts:</p>
<p>1) begin talks about graduate admissions with some faculty at his university prior to summer break. they will have a decent idea of his abilities and as such will give him an idea of where he should begin to focus his search as well as provide some ideas in terms of research going forward.</p>
<p>2) take the regular gre before fall simply to get it out of the way. math departments arent going to care much about the verbal and writing scores. so long as theyre both good enough to validate a command of the english language, all is good. math should be 780+, though this shouldnt be much of an issue.</p>
<p>3) download the practice gre math subject exam from the ets website and take it. the exam is NOT terribly difficult, but IS difficult to perform well on. the earlier that is known, the better. by that, i mean this: most good math majors will be able to look through the exam and find only a handful of questions they simply dont know how to do. however, some of the questions prove more difficult than they initially look and, more importantly, time is a MAJOR issue. reading a difficult question, getting in the mindset to attack it, figuring out how to solve it, actually solving it (without a calculator) and then quickly dropping the entire mindset to attack a NEW, completely different question (focusing on something you havent thought about in two years) is a skill that few have mastered. it will prove particularly important on the gre math exam. </p>
<p>4) over the summer, become aware of what 'within reach' programs have strengths in some of the general fields of interest. at that point in my search, for example, i was pretty sure i wanted to do something in discrete mathematics or logic/foundations. being able to narrow things down to 15 or so schools at this point will make contacting faculty somewhat less daunting.</p>
<p>5) take the real gre math exam early in the fall. the late date is too late for some programs and will give you no leeway to retake should the score not be as good as desired. on that note, the gre math score IS important, and you will even see this confirmed on many programs admissions pages (berkeley and penn come immediately to mind). much like with ugrad admissions, a top score will not ensure admission to a top school, but a score less than 700 or so will make it virtually impossible to get into a top 20 program.</p>
<p>6) dont kill yourself over determining a very narrow research focus. while putting forward strong interests is an important part of a good statement of purpose, more than in some other fields, phd programs are focused on admitting on the most brilliant students over smart students who will best fit into their labs.</p>
