Course Objective

The course objective of Science 101 is to cover topics in physical and biological science, such as the properties of matter, the fundamentals of thermodynamics, atmospheric science, foundations of biochemistry, cell processes and anatomy.

Grading Policy

Your grade for this course will be calculated out of 300 points. The minimum score required to pass and earn real college credit for this course is 210 points, or an overall course grade of 70%. The table below shows the assignments you must complete and how they'll be incorporated into the overall grade.

Assignment	Possible Points
Quizzes	100
Proctored Final Exam	200
Total	300

Quizzes

Quizzes are meant to test your comprehension of each lesson as you progress through the course. Here's a breakdown of how you will be graded on quizzes and how they'll factor into your final score:

You will have 3 attempts to take each quiz for a score.
The highest score of your first 3 attempts will be recorded as your score for each quiz.
When you've completed the course, the highest scores from your first 3 attempts at each quiz will be averaged together and weighed against the total possible points for quizzes. For instance, if your average quiz score is 85%, you'll receive 85 out of 100 possible points for quizzes.
After your initial 3 attempts, you can take a quiz for practice as many times as you'd like.
You will need to pass each quiz with a score of at least 80% to earn course progress for the lesson. However, it is not necessary to earn 80% within the first three quiz attempts.

Proctored Final Exam

The proctored final exam is a cumulative test designed to ensure that you've mastered the material in the course.

You'll earn points equivalent to the percentage grade you receive on your proctored final. (So if you earn 90% on the final, that's 180 points toward your final grade.)
If you're unsatisfied with your score on the exam, you'll be eligible to retake the exam after a 3-day waiting period.
You can only retake the exam twice, so be sure to use your study guide and fully prepare yourself before you take the exam again.

Items Allowed on Study.com Proctored Exam for Science 101:

Prerequisites

There are no prerequisites for this course.

Course Format

Science 101 consists of short video lessons that are organized into topical chapters. Each video is approximately 5-10 minutes in length and comes with a quick quiz to help you measure your learning. The course is completely self-paced. Watch lessons on your schedule whenever and wherever you want.

At the end of each chapter, you can complete a chapter test to see if you're ready to move on or have some material to review. Once you've completed the entire course, take the practice test and use the study tools in the course to prepare for the proctored final exam. You may take the proctored final exam whenever you are ready.

How Credit Recommendations Work

This course has been evaluated and recommended by both ACE and NCCRS for 3 semester hours in the lower division baccalaureate degree category. To apply for transfer credit, follow these steps:

If you already have a school in mind, check with the registrar to see if the school will grant credit for courses recommended by either ACE or NCCRS.
