Tests

  • review the entire book with 215 multiple-choice tests, taken from college entrance exams and entrance exams;
  • train quick reading of a statement: which formula, which restriction, which quadrant;
  • check each answer immediately, with a short explanation.

The tests are grouped by subject, in the same order as the chapters. Click on an alternative to see if you got it right; the explanation appears next. The acronym in parentheses indicates the origin of the test and the year (for example, ITA-72 is the exam from the Technological Institute of Aeronautics of 1972).

The statements were rewritten and all answers were checked. In some tests, the original answer key was wrong or the statement had a printing error; In these cases the explanation tells what the problem was and what the correct answer is.
