April 2019 subject test takers: how did you feel?

Postby bark_muffalo » Sat Apr 06, 2019 7:00 pm

Took the subject test this morning, feeling okay-ish. I thought the test was overall about as difficult as the practice exams, but that the first half was a bit easier than the first half of the two most recent published exams, and the second half a bit harder.

For others who took it, what are your thoughts on the exam/how you managed?

I felt it was a bit harder overall. I managed to blaze through most of the questions in about half the time, but there were about ten that I skipped initially so I could focus more time on them at the end. I figured out about five of them, and five of them I more or less guessed. Two of the combinatorics ones gave me problems, which surprised me, since that's my area. (I realized what my mistake was for on one of them while I was typing this.) There was one from analysis that I had absolutely no idea about. I'm sure there was some trick that I needed to apply, but I couldn't figure out what that was for the life of me. Other than that, most of the questions used the same tricks that came up in the practice tests. In this week leading up to the test, I took a practice test every day, and I think I must have done all of my practice tests a total of at least three times each. It may sound excessive, but it's very helpful for having the tricks come to you naturally and for answering questions quickly.

No, I agree with you. I retook the two most recently released practice exams and there were a couple of questions I managed to solve quickly (one of them was a combinatorics question) because the exact same tricks from the practice exam made them easy. However, there are always a couple of questions I miss because of some silly calculation error (I already realize I made such a mistake on at least one easy problem), so it's tough to estimate how well it went overall...now comes the agonizing wait for the results!

It was definitely harder in my opinion. I had been scoring in the 90th percentiles on all the practices, but I feel like I'll be lucky to get above 70th percentile here!
I'm not good with algebra and combinatorics, so those questions threw me off. I answered maybe 40 very confidently the first time around, then went back in the last hour or so and answered as many as I could, guessed on the remaining ones when time ran out. Made a couple careless mistakes along the way (sin(pi/3)=sqrt(3)/2, not 1/2...)

There are some tricky question involving counting the number of zeros/local extremes for some specific functions in the test I took (I assume they are all different). Had to guess on these. Only one complex analysis question I encountered (and no stoke's theorem, green's theorem or divergence theorem for some reason unknown :) )

In general it's easier than I expected (I used to thought that there are going to be more tricky complex analysis/algebra/graph theory). But that doesn't mean I did well. There are around 10 questions that I don't know how to do (but able to eliminate some obviously false answers), had to make guesses. I probably also messed up some other questions.... Hope I was lucky, but most likely I am going to take the test again. :roll: :roll: :roll:
Would hate myself if this test is easier than average and I blew it up.... :cry:

It sounds like we had the same version, and yeah, I also hope the test was not a below average version in terms of difficulty! I keep replaying questions in my head and waffling between cautious optimism and dread. I will likely have to retake it, but I hope that I didn't do embarrassingly badly.

Hi,

Could you briefly list the tricks that you think had to be used to solve the questions? It'd be great if you could provide a (comprehensive) list of the ticks on various types of questions.

I suck at remembering tricks to solve problems, and I'll be giving the test in Sept/Oct. Your advice will benefit me greatly.

A useful trick is to remember that a tough integral, from -a to a, is 0 if the function is odd

Anything else? It'd be great if we could get a list going. There's very little info about such tips/tricks.

Maybe make a separate thread for "GRE tips and tricks?"

If the integral is like that: V(a^2-x^2, trat it as the srea of the top part of s circle.

There is a guy on Youtube, BlackOenRedPen. He has very good tricks in his videos.

I am a tutor and I will post more tricks as soon as I remember them. But I would like to see other people’s one. Maybe they will know things that I don’t.

We can post tricks here. People will read thic thread. Later we can move them to a new thread. That was a good idea.

I posted a bunch of tips and tricks on my Twitter earlier this year: https://twitter.com/mathsubgre

I'm planning to start posting again sometime soon once things get a little bit less busy on my end.

(There are also a few brand new GRE questions on there; I was actually hoping that some people would try solving them before I put in the work of typing up more tips/questiosn and making them pretty. :P )

Just my opinion, but trying to list and remember a bunch of tricks is less helpful than doing a lot of questions that require those tricks, looking at hints to the ones you got wrong the first time around, seeing if you can then figure out the trick, and finally, looking at the solution if you remain stumped. Trying the latter approach will make remembering these tricks much easier, as they will become more a part of your mathematical intuition than mere tricks.

To that end, I strongly recommend checking out DMashura's website. He's got hints to every question from every published GRE, as well as links to nicely written up solutions from Ian Coley at UCLA. I used these resources a lot while studying for the exam, and in the (likely) event that I retake it, this will be the first place I turn to.
