If you consider yourself a lifelong learner, online courses are an easy and affordable way to hone your skills, challenge your brain, and maybe even discover a new interest or hobby. You can find e-courses on everything from interior design to graphic design, and many of these classes are free on websites like Udemy, Coursera, and edX. (But if you want a certificate to prove you completed the program, there is typically a fee attached.)

Ready to dive into some lesson plans? We’ve selected 10 of the coolest classes you can take right now from the comfort of your own home.

1. Dog CPR and First Aid

Many non-medical professionals are now CPR-certified, but did you know that similar first aid techniques can be used on dogs in emergency scenarios? This course covers CPR and the Heimlich maneuver for canines, as well as explaining how to read a dog’s vital signs. One of the lessons also addresses emergency prevention, including topics such as car safety, toxic foods and plants, and disaster preparedness. Whether you have a fur baby of your own or just want to be ready to rescue an animal in need, this is the course for you.

2. Neuroplasticity: How To Rewire Your Brain

Old habits die hard, but it’s still possible to make meaningful, lasting change in your life. Taught by psychologist and Brain Academy founder Gregory Caremans, the course is ideal for anyone who wants to form healthier habits, minimize painful memories, or stop procrastinating (indeed, there’s a whole chapter dedicated to this last topic). No prior knowledge is necessary, but be prepared to give your brain a full workout. The class includes lots of exercises that will help you reshape your brain in the most literal sense.

3. The Science of Well-Being

After you’re done rewiring your brain, you can teach it how to be happier with this class from Yale University. Psychology professor Laurie Santos starts off by refuting common misconceptions about the things we think will make us happy, despite scientific evidence to the contrary. Fortunately, these biases of the brain can be overcome, and a large chunk of the class is dedicated to strategies that can be used to achieve a greater sense of well-being.

If Santos's class leaves you wanting more, you can also sign up for The Science of Happiness, a free class from the University of California, Berkeley's Greater Good Science Center. It's available on edX for free (with an option of buying a $49 certificate upon completion).

Sign up for Santos's course on Coursera for free. The optional certificate costs $49.

4. The Rise of Superheroes and Their Impact On Pop Culture

If you’re still mourning the loss of legendary comic book creator Stan Lee, you may enjoy this course from SmithsonianX, which features some of the superhero-themed knowledge that Lee imparted during his time on this Earth. You’ll also hear from another comic book maven, Michael Uslan, who served as executive producer of The Dark Knight series and The Lego Movie. After six weeks, you’ll be able to explain how the birth of the first-ever superhero in 1938 launched a global phenomenon that continues to inform art, pop culture, and even ethics.

Sign up on edX for free. The optional certificate costs $50.

5. Greatest Unsolved Mysteries of the Universe

What caused the Big Bang? What is our universe made of? Is there life in outer space? Two astronomers from the Australian National University set out to address some of the lingering questions in modern astrophysics. You may walk away from this course with more questions than answers, but you’ll have a more informed take on life’s greatest mysteries, as well as a better understanding of why exactly they’re so tough to crack.

Sign up on edX for free. The optional certificate costs $50.

6. The Kennedy Half Century

Calling all history and presidential trivia buffs: This course from the University of Virginia provides a comprehensive understanding of the legacy that John F. Kennedy left behind. It covers J.F.K.’s rise to power, presidency, and assassination, and explains how these momentous events have had a long-lasting impact on the public, media, and presidents who came after him.

Sign up on Coursera for free. The optional certificate costs $49.

7. The Science of Beer

If Alton Brown was to teach a class on beer, it would probably look similar to this offering from Wageningen University & Research in the Netherlands. You’ll learn how your beloved brew of choice is made and what exactly makes it taste so delicious. Fair warning, though: You’ll also learn about some of the unsavory health effects of imbibing too much beer. There’s a business angle, too—instructors provide an overview of how beer ends up in the supply chain and how marketers try to influence consumer behavior.

Sign up on edX for free. The optional certificate costs $49.

8. The Music of the Beatles

With 13 studio albums to their name, The Beatles released enough material to dissect, analyze, and enjoy for decades to come. This class from the University of Rochester charts the band’s evolution as musicians, from their early experiences in Liverpool and Hamburg to their psychedelic phase to the release of Abbey Road, the last album they recorded. (Although, as you’ll likely learn in this course, Let It Be was the last album they actually released).

Sign up on Coursera for free. The optional certificate costs $49.

9. Aquaponic Gardening: Growing Fish and Vegetables Together

Healthy, sustainable food doesn’t always come cheap, so why not raise your dinner in your own backyard? Author and aquaponic gardening expert Sylvia Bernstein will guide you through the basics of raising fish like tilapia, bluegill, and catfish in captivity. In turn, the waste from those fish can be used to nurture an entire fruit or vegetable garden. Sylvia and her husband, Alan, will demonstrate the eco-friendly techniques you’ll need to know to yield a bountiful feast.

Sign up on Udemy for $25. A certificate of completion is included in the price.

10. Passive Income: Top 10 Legit Ways to Make Money Online

Everyone wants to know how to make more money with less effort. Entrepreneur and IT professional Victor Gorinov's Udemy class is designed to help you figure out how to do that. He’ll introduce you to the basic concepts involved in earning passive income, tackling options like affiliate marketing, domain trading, investing in stocks and real estate, monetizing your YouTube account, and selling your photos and videos to stock image websites.

Sign up on Udemy for $12. A certificate of completion is included in the price.

Hundreds of Kangaroos Roam the Green at This Australian Golf Course

Anglesea Golf Club has all the makings of a regular golf club: an 18-hole golf course, a mini golf course, a driving range, a clubhouse, and a bistro. But the kangaroo mobs that hop around the holes add an element of surprise to your otherwise leisurely round of one of the slowest games in sports.

According to Thrillist, the kangaroos have been a mainstay for years, and the club started giving tours a few years ago to ensure visitors could observe them in the safest way possible. For about 25 minutes, a volunteer tour guide will drive a golf cart with up to 14 passengers around the course, sharing fun facts about kangaroos and stopping at opportune locations for people to snap a few photos of the marsupials, which are most active in late afternoon and early morning. Kangaroos are friendly creatures, but Anglesea’s website reminds visitors that “they can also be quite aggressive if they feel threatened.”

Post-graduate students and academic staff from Melbourne University’s zoology department have been researching Anglesea’s kangaroo population since 2004, and some of the animals are marked with collar and ear tags so the researchers can track movement, growth, survival, and reproduction patterns throughout their life cycle.

One of the reasons kangaroos have continued to dwell on land so highly trafficked by people is because of the quality of the land itself, National Geographic reports. The golf course staff regularly sprinkles nitrogen fertilizer all over the green, which makes the grass especially healthy.

If you decide to plan a trip to Anglesea Golf Club, you can book a kangaroo tour here—adult tickets are $8.50, and children under 12 can come along for just $3.50 each.

From Downton Abbey to Friends: How Much Your Favorite TV Homes Would Cost In Real Life

If you've ever wanted to live like the lords and ladies of Downton Abbey, you'd better be prepared to shell out some serious cash. With 61 bedrooms to accommodate the Abbey's many residents—not to mention the regular procession of notable house guests (and the occasional group of convalescing soldiers)—£137 million, or $173.9 million, for Downton Abbey's grand estate almost seems like a steal.

If you're really serious about buying Tony Soprano's spread, you can: the North Caldwell, New Jersey home hit the market earlier this year with an asking price of $3.4 million (despite the fact that, as global construction supplier Burton Roofing points out, comparable houses in the area tend to sell for about half that price).

But living like the characters in your favorite TV series doesn't have to cost a fortune. To prove it, Burton Roofing crunched the numbers to determine just how much your favorite television homes would cost in real life, in case you want to start socking away for that down payment. (If you're thinking about taking up residence in Walter White's cozy Albuquerque abode from Breaking Bad, just be prepared to budget in a little extra for what it will take to clean all those fan-thrown pizzas off the roof.)
