• Coronavirus update - The coronavirus epidemic affects us all in multiple ways. Some of us are more vulnerable or nervous or skeptical than others. I believe in respecting your choices while explaining mine. My personal choice was to limit all unnecessary interpersonal contact while any locality that I live in has more than a 1% active infection rate. [...]
  • “How much will I improve” on the SAT / ACT / GRE / LSAT / GMAT? - When you first start preparing for a standardized exam, you usually take an entrance test.  It’s usually lower than what you had hoped for, and then you wonder, “How many points can I expect to gain?”  That is a very good question, and also a complicated one.  It doesn’t make sense to measure improvement in [...]
  • An ACT Essay Prompt Simulacrum - The ACT changed its essay format last year.  It is difficult to get much practice for this essay, because so far the ACT has only published two samples:  Intelligent Machines and Public Health and Individual Freedom (p. 54).  Here I provide a simulacrum, an unofficial sample prompt.  I made every effort to write this simulacrum [...]

  • Why my 6-week classes cost less, and why that’s good - As a small, local test-prep company, one of my business strategies is to be a price leader.  To take a GRE class at a major test-prep company like Kaplan, Princeton Review, Manhattan, or Blueprint, you can expect to pay anywhere from $900 to $1,800.  You can take an equivalent class at Nth Degree for $600, including [...]
  • Tests for Divisibility by 4 or 8 - There are many occasions in math problems when it is useful to know if one number is divisible by another.  For example, if you can tell at a glance that 3,521 is not divisible by 11, then you will not waste your time trying to divide 3,521 by 11!  Or if you need to reduce [...]
