Three Ways to Study Biology Online

There is a biology program for every situation, from students who want to prove their knowledge via certificate or pursue lifelong careers in the field to those who simply want to learn more. Here are some of the reasons why students might choose to take a particular path.

Certificate For-credit Informational
Description Certificate classes are unique because they verify one has passed a given course. Many online biology classes offer verified certificates for a fee. Some online biology courses award college credit to successful learners. Most for-credit classes are available through traditional colleges and universities. Informational classes enhance knowledge, but do not award certificates or college credit. Some colleges allow students to audit online biology courses at no cost.
Who takes this type of course? A certificate course is ideal for professionals who want to learn more about a given area of biology, but would like a way to verify their studies to employers. Students enrolled in for-credit online biology courses are usually do so over the course of a formal degree program. Informational biology classes suit students who have a natural curiosity, or work in a field where additional knowledge is helpful, but not required.

Why Take an Online Class in Biology?

From professional marketing or personal enrichment to advancing their degrees, there are many reasons students might take biology courses online. Here are some of the most compelling.

1. Efficient method of learning a biological specialization
Medical and biology professionals explore various issues, problems and situations with which they might be unfamiliar. An online class is ideal for situations where browsing a textbook is insufficient, yet enrolling in a full program is overkill. Online courses allow students to gain much-needed knowledge in a practical, manageable learning medium.
2. Students don’t have to choose between education and work
Online degrees are growing in popularity as students realize just how valuable and flexible they can be. Online learning is a boon to working professionals for whom classroom attendance is difficult, including working professionals who want to gain additional knowledge without sacrificing work and research experience.
3. Wide selection of subjects within the biology field
Biology has many sub-disciplines that often interact. An environmental scientist might need to know a great deal about microbiology, for instance. How can that scientist gain the in-depth knowledge necessary on microbiology without having to earn another degree? Stand-alone online biology courses can help scientists expand their knowledge base and enhance their work.

Must-Have Apps & Podcasts for Learning Biology


Biology is not an easy science to learn; some of the smartest minds in the world are still trying to figure out how certain biological processes work. This means students and professionals within the biology field will probably appreciate all the help they can get. The following list of apps can make learning about biology a little easier.

\nScience Dictionary\n


This app is an excellent resource for anyone studying or working in science, including biology. It defines key scientific terms alongside audio pronunciations and images.

\nComplete Biology\n


Complete Biology is a comprehensive app aimed at high school and college students. Features include practice test questions, tutorials and common formulas. This app is an excellent study tool for biology coursework.

\nGene Screen\n


In addition to teaching about genetics and heredity, the Gene Screen app offers calculators for determining the prevalence and inheritability of certain diseases and genetic traits.

\nBasic Statistic\n


Basic Statistics is not a true biology app, but it’s very useful for those in the academic or professional biology realm, thanks to the prevalence and importance of statistics in the study of biology. Much of the app consists of explanations and notes of fundamental statistical concepts.



We may know a great deal about biology, but much of the natural world is still a big mystery. One of the interesting points about podcasts is that the hosts and guests often explore these mysteries, expound upon the most recent discoveries, and offer innovative ideas and solutions to today’s issues. Here are some podcasts sure to pique scientists’ and biology enthusiasts’ interest.

Expert Advice for Taking Online Biology Courses

Arvin Vohra

You’ve created many online biology courses. What are your key considerations when building them? The biggest mistake people make in creating online biology courses: they try to mimic the classroom setting. In other words, they take the most boring, least effective method of education on earth, and then digitize it. Instead, use tutoring as your starting point. Our Vohra Method courses, for example, are based on rigorous, Socratic style tutoring. Khan Academy courses are inspired by the more familiar didactic style of tutoring.
What about lab work? Depending on your goals, you can get the benefits (if any exist) of the lab parts of a non-online biology course either by watching videos of labs, or by interning at a research lab. Watching a few demonstration videos can help solidify your understanding of abstract concepts. Working at a lab can show you how tedious working at a lab can be, and help you decide if you actually want to do that.
What are some of the best online biology certifications or courses for professionals who want to advance their careers? College graduates and those that opted out of college should consider the GRE Biology Test. Like the AP, this is a knowledge and understanding test. You don't need to have a Bachelor's degree or have had any number of in-class hours. It just measures what you know, not how much time you've squandered in a traditional classroom.
Anything else you want to say about online biology programs? Online education is the future. It is already doing to non-online education what Netflix did to Blockbuster. Even students in traditional schools rely on online videos by world-class teachers instead of on their school classes. Subjects that are both information-dense and concept-heavy, like biology, particularly benefit from the online approach.
