All colleges in the US accept either the ACT or the SAT scores and do not give a preference to either test. Standardised test scores are particularly important for international students as most apply from school systems with different grading criteria. Median and/or mean SAT/ACT scores of students who get accepted at top-ranked and selective colleges are in the highest percentiles.

The common question then, which frequently arises, is which test to take?

Total score ranges from 400-1600 Total score ranges from 1-36

The essay section is optional with three scores. One score each for reading, analysis, and writing, between 2 and 8 The essay is optional on a scale of 1-36.

  1. Take the test on which you can score higher
  2. Each test has pros and cons
    • Good at reading, but a science-phobe? Think of the SAT
    • Math – is algebra a challenge? Think of the ACT
  3. Overall ACT has more time pressure but the questions tend to be more straightforward
  4. Reading passages on the SAT are more dense, and harder questions tend to be more tricky
  5. Take a full-length ACT and SAT to really determine which test works for you
  6. Its not a question of which test is easier, its a question of which test you can score higher on
  7. Getting a 90+ percentile score on either test requires focused practice, time, and in-depth test analysis
