Please note that there are two Sample Midterms posted in StatsPortal in the Resources section for those of you in the classroom lecture sections of the course. For some reason, these are not posted for those of you who are taking the course by distance. It is still not even clear whether or not those of you in distance will be writing a similar exam or, perhaps, a shorter one. Make sure, if you are in distance, that you contact your prof to clarify what exactly is happening for the first midterm. If you have an option of writing it on campus or online at home, I strongly recommend you write it on campus. The online quizzes in the past have been often affected by technical problems, and difficulty with reading the questions and submitting the answers. I would much rather have a physical exam to write.
By the way, I am almost sure that the midterm exams for Stat 1000 last year were 2 hours long, not just 1.5 hours. I am therefore surprised to see that your sample midterms still have 40 questions. You may want to double-check with your prof how long the exam is going to be and how many questions it will have.
Here is a link where you can download the Sample Midterms if you haven't found them in StatsPortal. Note that they do include an answer key on the last page:
