Study Aids & Courses for the National (ASBOG®) Geology Licensing Exam,
the California Specific Exam and
the Hydrogeology & Engineering Geology Certification Exams


  • Please note we will no longer be offering on-site courses during the winter. If you wish to take an onsite course you will need to register for a summer class.

  • Ideally you would begin studying about 6 months in advance. The course gives you the focus and direction needed to streamline your studying process.

  • Don't wait to hear if you have been accepted to take the exam because in most states acceptance letters typically come out 2 to 4 weeks before the exam. Plan ahead.

  • Winter, 2020 ASBOG® exam review courses have been posted! Sign up early to secure a seat.

  • ASBOG ® Candidate Handbook revised, 2016
