Official Requirements for High School Students
For the vast majority of high school students in Alberta, the path to taking Biology 30 requires successfully completing Biology 20 first. The provincial curriculum is designed with this sequence in mind, ensuring students have a solid foundation before tackling more advanced topics. A minimum passing grade in Biology 20 (often 50%, but a higher grade like 65% is recommended for success) is the standard entry requirement for most schools.
Why the Prerequisite is in Place
The sequential nature of the biology courses is intentional. Biology 20 focuses on fundamental concepts that are essential for understanding the advanced material in Biology 30. Topics covered in Biology 20, such as photosynthesis, cellular respiration, and basic human systems, provide the building blocks for the more complex genetics, molecular biology, and regulatory systems explored in Biology 30. Skipping the prerequisite would mean attempting to build a house without a foundation, making the more difficult course an academic struggle. The official structure is designed to maximize student success and prepare them properly for the diploma exam and potential post-secondary studies.
Exceptions for Adult and Special Circumstances
While the prerequisite is strict for traditional high school students, there are specific scenarios where it can be bypassed. Understanding these exceptions is crucial for non-traditional students or those facing unique situations.
- Adult Students (Age 20 or Older): The Government of Alberta offers flexibility for adult learners. If you are 20 years of age or older, you can register for and complete Biology 30 without having first completed Biology 20. Upon successful completion of Biology 30, you will automatically receive credit for the prerequisite Biology 20 course as well. This policy facilitates academic upgrading and is a key option for mature students.
- Principal's Discretion: In very rare cases, a school principal may be willing to waive the prerequisite for a student. This would require a compelling argument demonstrating why the student cannot take Biology 20 and has the skills necessary to succeed in Biology 30. This is not a common occurrence and is not something to rely on for your course planning.
- Upgrading Programs: If you are a high school graduate but need to complete the prerequisite for a post-secondary program, many academic upgrading institutions offer the Biology 20 course. This is a common and reliable pathway for students who initially did not take or pass Biology 20.
Bio 20 vs. Bio 30: A Comparison
Understanding the distinct focus of each course helps explain why the prerequisite is so important. Biology 20 lays the groundwork, while Biology 30 delves into more complex, interconnected systems and advanced genetic principles.
| Feature | Biology 20 | Biology 30 |
|---|---|---|
| Core Theme | Energy and matter exchange | Adaptation and change |
| Topics Covered | Ecosystems, human organ systems, photosynthesis, cellular respiration | Nervous and endocrine systems, reproduction, genetics, population dynamics |
| Difficulty | Introductory concepts; considered a significant academic step up from Science 10 | Advanced concepts; a notable jump in difficulty from Bio 20, requiring extensive memorization |
| Emphasis | Building foundational understanding of biological processes and interactions | Exploring complex systems, advanced genetics, and regulatory mechanisms |
| Post-Secondary Relevance | Generally a prerequisite for Bio 30; not typically sufficient for university science programs | Often a specific prerequisite for post-secondary science and health-related programs |
What to Do If You've Skipped Bio 20
If you are a high school student who did not complete Biology 20, you have several options depending on your long-term goals.
- Talk to your Guidance Counselor: This is the first and most important step. They can help you understand your specific situation, discuss your academic goals, and lay out a realistic path forward. They can also advise you on whether an exception is possible, although it is unlikely for most high schoolers.
- Take Biology 20: The most straightforward approach is to complete Biology 20. It can be taken during a regular school semester, through summer school, or via an online learning provider. This ensures you have the necessary knowledge base for success in Biology 30.
- Consider Academic Upgrading: For adult students or those needing to complete the prerequisite after high school, upgrading services are available. Institutions like Chinook Learning Services or SAIT offer these courses.
- Explore Alternative Science Courses: If you realize you do not need Biology 30 for your post-secondary plans, you could consider taking Science 20 instead. This can fulfill the general Grade 11 science requirement for the Alberta High School Diploma, though it is not a direct substitute for Biology 20 if you later decide to pursue Bio 30.
It is strongly recommended to fulfill the prerequisite requirement rather than seeking an exception, as the foundational knowledge from Biology 20 is crucial for understanding the more demanding content in Biology 30. The curriculum is structured to build on previous learning, and students who skip Bio 20 are at a significant academic disadvantage.

Conclusion
The short answer to "do I need bio 20 to do bio 30?" is almost always yes, especially for traditional high school students in Alberta. The course sequence is intentionally designed to ensure academic success by building foundational knowledge. While exceptions exist for adult learners and in rare circumstances with a principal's approval, the best path is to complete the prerequisite. This ensures you are fully prepared for the increased difficulty and complex topics of Biology 30, paving the way for success in the diploma exam and your future post-secondary pursuits.
Practical Steps to Take
If you are currently a high school student and have not yet taken Biology 20, the following steps are recommended:
- Consult your school's guidance counselor immediately to plan your course schedule.
- Evaluate your post-secondary goals to confirm if Biology 30 is truly required.
- Enroll in Biology 20 in an upcoming semester, a summer session, or through an online program.
- Commit to strong study habits in Biology 20 to prepare for the leap in difficulty to Biology 30.
- Review course outlines from schools or online providers to understand the content and what is expected.
