Diagnostics Exams


Diagnostic tests in calculus and statistics will be administered for ALL NEW STUDENTS. Students are strongly encouraged to review the key topics in calculus and statistics during the summer. Exams are primarily multiple choice and calculators are not permitted. Students will have 1 hour and 15 minutes to take each test. Only students who have successfully completed prerequisite-level courses in calculus and statistics may take the diagnostic exams. Successful grades on prerequisite level courses and diagnostic exams will allow students to enroll in graduate level courses (ENVIRON 710 Applied Data Analysis and ENVIRON 520, Resource and Environmental Economics) requiring calculus and statistics as prerequisites.

Those students with low scores relative to their peers will be required to engage in self-study or take remedial coursework prior to diagnostic retesting and preparation for enrollment into various ENVIRON classes with statistics and/or calculus as prerequisites. Avoid this and study ahead of time.

Diagnostic tests in calculus and statistics will be administered Wednesday, July 7 – Friday, July 30. Students can take exams at any point during the exam window.


Eligibility
  1. Only students who have successfully completed prerequisite-level courses in calculus and statistics may take the diagnostic exams.
  2. Students who are almost done with their summer prerequisite course(s) may take the online diagnostic exams this summer, if they feel prepared to do so. However, in this scenario, the student must be more than 75% done with their prerequisite course and on track to earn a passing grade. 
  3. After the exam window in summer 2021, the next opportunity to take the diagnostic exams will be in summer 2022.

Please Do Not Stress! This cannot be emphasized enough. Although we want students to do well on the diagnostic exams, please do not stress about these tests in advance. The exams are only intended to assess where students are in these subjects at the time that they enroll, and to make sure that students are prepared for graduate level courses requiring calculus and statistics as prerequisites.


Failed the Exam(s)?

If ENVIRON 710 is required by the program area, and you fail to pass the statistics exam, you will need to take a remedial course, audit a remedial course or otherwise study sufficiently to improve their knowledge in statistics and earn an adequate score on a retest.  If you earn an adequate score on the retest they will be permitted to enroll in ENVIRON 710 the next time it is offered.

If ENVIRON 520 is required by the program area, and you fail to pass the calculus exam, you will need to take a remedial course, audit a remedial course or otherwise study sufficiently to improve their knowledge in calculus and earn an adequate score on a retest. If you earn an adequate score on the retest they will be permitted to enroll in ENVIRON 520 the next time it is offered.


Key Topics in Calculus and Statistics

We encourage students to review the key topics in calculus and statistics over the summer. You can do this by reviewing the key topics in college level textbooks, working through practice problem sets or taking free online courses (where available). View key topics in calculus and statistics (as well as topics in other prerequisite courses, as needed).

Exam Dates/Times & Preliminary Instructions

Diagnostic tests in calculus and statistics will be administered Wednesday, July 7 – Friday, July 30. Students can take exams at any point during the exam window.

You can decide when to take both exams during this window. Both exams can be taken on the same day if you choose. 

Before the exam window opens, we will provide you access to take a sample exam in Sakai so that you can test your internet connection and to make sure that you can navigate Sakai. Please note that limited tech support will be available over the weekend so please keep this in mind when choosing your test date(s).

The diagnostic evaluation is an advising tool to assess your background and knowledge of calculus and statistics.

Keep in Mind

  1. You are not permitted to use books, notes, other exams or calculators during the exams
  2. Questions are primarily multiple choice
  3. You will not need a calculator for the exams
  4. You have 1 hour and 15 minutes to complete each exam
