>>13030708I'm ignoring your requirement of better than 80% because more data is helpful
Took it early November 2020
30% geometry - (study more)
30% algebra/groups
20% stats/calculus/graphs/estimation - (study more)
10% straight calculus
My older brother got the practice book you can buy on the ets site, and it's good material to study if you want to have an idea of the exact type of questions. I flipped through lightly 2 days before but didn't do much studying because I only needed 151 or better on quantitative reasoning. I felt confident enough because I had a perfect math section on the ACT and made like 95% A's and 5% B's in all my math classes.
I made a 160 (>72%) without doing anything other than skimming their practice book for it, so really it depends on your personal goal for a score because different grad programs may be more or less selective or require different scores. I'm finishing my 1st semester of grad school in 2 weeks. My brother is about the same as me mathematically, studied the ets book 2 hours a day for a week, and he made a 165 (>85%) he didn't end up going to grad school because he graduated 2 years ago and the job market wasn't wrecked from covid.
In regards to
>>13032579To me, costs are more important than program ranking (you may feel different). If you care about getting into a high ranking program, you should have already gotten into a high ranking undergrad program that will expedite that path without fear of rejection. Different schools will pay different amounts relative to their local costs of living depending on if you do research/teaching assistance/grading/etc.
As far as test availability, just make an account on the ets site to register and you should be able to enter a zip code and click a calendar to see when tests are available that day. This is highly variable depending on where you live and how strict covid restrictions are.
Also foreigners prepare so much because it's their ticket out of a shithole country.
