Test 1 will be offered online from 11:59 pm of 7/22/2025 to 11:59 pm of 7/23/2025. You have 110 minutes to complete the test once you start the test.1• You need to enable Honorlock to take the test. If you have any issue in lockdown browser, please contact 956-872-2598 for help.• Please do the following to take the tests:(1) Log into Blackboard with your STC credentials.(2) Scroll down to “Test 1″ and click on “Test 1″. (You need to enable Honorlock to take the test.)(3) You have 110 minutes to complete the test.(4) The test will cover chapters 5, 6, 7, and 8 of Vol 2 of the textbook.(5) You can use calculators during the test but it is a closed book test. You can use the formula sheets provided by me during the test.(6) For multiple choice questions (question 1 to question 10) in Test 1, you only need to select the correct answers.(7) For free-response questions (question 11 to question 13) in Test 1, you need to show the procedures to obtain your answers. You input the procedures through the boxes below the questions. It would not get full credit for solutions that only have answers but not procedures to obtain the answers.(8) After you complete the test or before the 110 minutes are up, you make sure to submit your test. Please don’t email me your solutions for free-response questions to my email at gxu@southtexascollege.edu.(9) It is your responsibility to make sure that you have submitted all your answers. Once you leave the test site, please don’t email me any more of your answers for the test. The above regulations are just for protecting honest students. Being honest is our best help to make the whole class to be fair and consistent to everyone. Hope this is understandable. Have a pleasant and successful summer term.
