Being prepared is the best way to ease the stress of test taking. If you are having difficulty scheduling your Placement Test, please contact the UNG Testing Office. If you have a red yes in any Placement Test Required row on your Check Application Status page in Banner, read the information below relating to the area in which you have the red yes. Establishing Connection... MTTC tests are meant to ensure that each certified teacher has the necessary skills and subject area knowledge to serve in Michigan's schools. These tests are designed and implemented by the Michigan Department of Education. Save all official MTTC score reports in a safe place because you may need them for employment or teacher certification in other states. If you need new score reports, additional copies may be ordered using these instructions. In order to be certified, students must pass the MTTC subject area tests that correspond to the major and minor field(s) of study. These tests should not be taken until the final year of the program, but it is highly recommended that students pass their MTTC subject area test(s) before student teaching.
Elementary Education StudentsStudents seeking elementary certification must also take the Elementary Education MTTC test #103. Do not take the new Lower or Upper Elementary tests 117-124. When registering for the Elementary Education test, report elementary education as a "major." Take the time to review the online study guide and test objectives. Spend extra time studying for these subareas, which have lower pass rates:
Special Education Program StudentsCandidates interested in teaching grades 9–12 special education in a Michigan public school may need to take additional MTTC tests later in consultation with the hiring school (mathematics, integrated science, and/or language arts). If you have questions, contact Calvin's certification and assessment coordinator at (616) 526-6208 or certification@calvin.edu. The questions that follow are designed to make prospective students aware of the mathematics background required for those intending to take one of the SFU Calculus courses: MATH 150, 151, 154 or 157. The actual test will cover the same concepts as this practice test does, but the questions will be different. For more information about the expectations, read Calculus Readiness Test Assessment Topics. If you do not achieve a passing score on the actual test, we recommend that you enroll in Math 100 course, Precalculus. Treat the Practice Calculus Readiness Test as a learning experience: if your answer to a question is incorrect, make sure that you understand the concept the question is related to before attempting the actual test. You should be aware of the following conditions when you attempt this practice test:

There is one rapid, point-of-care test that looks for both antibodies and p24 antigen, in a similar way to antibody/antigen laboratory tests. The Determine HIV-1/2 Ag/Ab Combo was originally introduced in 2009, with an updated version that is now called the Determine HIV Early Detect launched in Europe in 2015 (the older version is still marketed in the United States and in some parts of the world).
The promise of having a ‘fourth-generation’ point of care test that detects p24 antigen is that the window period should be shortened. However, several studies found that although the older version of this test performed well in respect of established HIV infection, its ability to detect recent HIV infection did not match that of laboratory antibody/antigen tests. The test was quite insensitive to p24 antigen, making it only marginally better than antibody-only tests in detecting acute (recent) infection.
"All HIV tests need to have reactive results (a preliminary positive result) confirmed with further tests."
The handful of studies published so far on the newer version suggests it has better performance in acute infection, although it still does not match that of antibody/antigen laboratory tests. The Determine HIV Early Detect’s sensitivity during acute infection has been variously estimated to be 28% (in three African countries), 54% (France), 65% (the Netherlands) and 88% (UK).
An analysis pooled the results of 18 separate studies in which a point-of-care test (including Determine, OraQuick, UniGold and INSTI) was compared with a more sensitive laboratory test. Compared with fourth-generation laboratory tests, the estimated sensitivity of the point-of-care tests was 94.5% (95% confidence interval 87.4-97.7) and specificity was 99.6% (99.4-99.7). Compared with RNA (viral load) tests, the estimated sensitivity was 93.7% (95% confidence interval 88.7-96.5) and specificity 98.1% (95% CI: 97.9-98.2).
Sensitivity was higher in nine studies conducted in African countries than in the nine studies conducted in the United States and other wealthy countries. This is likely to be due to different populations coming forward for screening. Whereas 4.7% of those testing positive in African studies had acute (recent) HIV infection, this figure rose to 13.6% in the high-income countries.
A study in five African countries found that the performance of point-of-care tests was sub-optimal. Samples from some countries were more likely to have false positive results than others, suggesting that tests need to be locally validated and that some tests may be more accurate in relation to some HIV subtypes than others. The researchers found a high number of false positive results, whereas false negative results were relatively rare. The specificities of the First Response HIV Card Test 1–2.0, INSTI HIV-1/HIV-2 Antibody Test, Determine HIV-1/2 and Genie Fast HIV 1/2 were all between 90 and 95%. The findings confirm that the diagnosis of HIV should not be based on results from a single HIV rapid diagnostic test. A combination of HIV tests, and more specifically an algorithm (sequence) of two or three different tests, is required to make an HIV-positive diagnosis. This is recommended in testing guidelines.
All HIV tests need to have reactive (preliminary positive) results confirmed with confirmatory tests. A particular challenge healthcare workers have with rapid tests is how to communicate a reactive result to the person testing (who may be present while the result is being read) and explain that supplementary tests are needed. These problems are less frequently faced with laboratory testing – a large enough blood sample was taken to allow for it to be tested several times and for uncertainties in the diagnosis to be resolved.
The window period refers to the time after infection and before seroconversion, during which markers of infection (p24 antigen and antibodies) are still absent or too scarce to be detectable. Tests cannot reliably detect HIV infection until after the window period has passed. All tests have a window period, which varies from test to test.
Delaney and colleagues estimated window periods for a handful of rapid tests in a 2017 study. However, all these estimates were based on testing blood plasma. In practice, tests are usually done on fingerprick blood (obtained by pricking the finger with a lancet) and the window period is likely to be several days longer.
The fourth-generation Determine HIV-1/2 Ag/Ab Combo was estimated to have a median window period of 19 days (interquartile range 15 to 25 days). This indicates that half of all infections would be detected between 15 and 25 days after exposure. Ninety-nine per cent of HIV-infected individuals would be detectable within 43 days of exposure.
The third-generation INSTI HIV-1/HIV-2 test was estimated to have a median window period of 26 days (interquartile range 22 to 31 days). This indicates that half of all infections would be detected between 22 and 31 days after exposure. Ninety-nine per cent of HIV-infected individuals would be detectable within 50 days of exposure.
Several second-generation tests, such as OraQuick Advance Rapid HIV 1/2, Clearview HIV 1/2 STAT-PACK and SURE CHECK HIV 1/2 were evaluated. The median window period was 31 days (interquartile range 26 to 37 days). This indicates that half of all infections would be detected between 26 and 37 days after exposure. Ninety-nine per cent of HIV-infected individuals would be detectable within 57 days of exposure.
UK guidelines take a cautious approach, describing the window period for all rapid, point-of-care tests as 90 days.
If you are testing with a rapid, point-of-care test and you are concerned that you may have been exposed to HIV during the test’s window period, you could also be tested with a fourth-generation laboratory test. This requires a blood sample, taken through a needle from a vein in the arm, which is tested in a laboratory using a more sensitive test. The results should be available after a few days.
Performance of rapid tests is poorer in a number of situations. Results may not be accurate.
There are three possible test results:
1) Negative (may also be described as ‘non-reactive’). The test did not find any evidence of HIV infection. You probably don’t have HIV (so long as you aren’t testing in one of the situations described in the last section).
2) Reactive (often incorrectly described as ‘positive’ by manufacturers). The test assay has reacted to a substance in your blood. This does not necessarily mean that you are HIV positive. It means you need to take more tests to confirm the result. These extra tests are best done at a healthcare facility where they have access to the most accurate HIV testing technologies.
3) ‘Indeterminate’, ‘equivocal’ or ‘invalid’. The test result is unclear. Another test needs to be done.
The questions that follow are designed to make prospective students aware of the mathematics background required for those intending to take courses that are designated as Quantitative/Analytical (Q courses). The actual test will cover the same concepts as this practice test does, but the questions will be different. For more information about the expectations, read Q Assessment Topics.
If you do not achieve a passing score on the actual test, you will be required to enroll in and pass the course FAN X99: Foundations of Analytical and Quantitative Reasoning prior to taking any Q courses at SFU.
