Feedback Unfortunately you didn’t get over a 70% on your first examination (70% is passing at
StraighterLine). That’s okay, though. You can retake this 1st exam for a higher score (you’ll
need to wait at least 24 hours to retake). Now that you have a sense of what the course
assessments are like, consider making a study plan to tackle the content. The course
resources are an essential tool in course preparation. Be sure to set aside enough time to
study, have a quiet, distraction free area to take your exam, and be well rested before you take
any assessment in the future. Never hesitate to reach out and contact our helpful staff.
