Do You Make These Mistakes?

Who needs to study when we have "chemistry"?

Study Groups are great - in theory.  But...

  • How much work actually gets done?
  • Are you slowed down by students not as serious as you?
  • Who knows if you are using the right formula?
  • Who has the right answer when you are stuck?


Office Hour with your professor is valuable.  But...

  • How many other students are competing for your professor's attention?
  • What happens if you need more time to actually understand?
  • Is your professor annoyed you aren't getting it?


Pulling an all-nighter gives you lots of time.  But...

  • Staying up all night to study is a bad idea!
  • Cramming last minute for an exam is a bad idea!


Ask your parents for homework help.  But...

  • How long has it been since they took chemistry?

Build a Foundation in Chemistry You Can Be Proud Of!

Don't waste your money

You could hire a chemistry tutor.  Or enroll in small group tutoring through an educational consultant company.

  • Private Chemistry Tutor:  $35-$75 an hour
  • Small Group Tutoring Company:  $40-$130 an hour


Instead, take this course.  You will learn the lingo and understand the vocabulary any chemistry professor will throw at you and

  • Go into any first year chemistry class with confidence!
  • Navigate chemistry class like a pro!
  • Ace chemistry class!

Testimonials

“Chemistry is hard for me, and my teacher wasn't helping. Everyone in class is stressed out. These videos made me understand much better, and I think I will get an A!”

High School Student

Got my grade back up

“I don't want to waste time in a study sessions with students who aren't as serious as I am. I don't want to try to work around a private tutor's schedule, even if I could afford it with my college student budget. Joy Lab is the answer.”

University Student

Better than a private tutor

“I was frustrated with my son's chemistry class - he spent hours working on chemistry, yet continued to get poor grades on tests. I couldn't even help him with the homework. Now that he is working through the chemistry videos, he understands and is less bad-tempered. There is peace in our home!”

Parent

My son understands now

Work Smarter

Don't waste your time

The single most important factor for determining success in chemistry is how many problems worked.

There is no magic number.  Each student has to work as many chemistry problems as it takes until the problems become "easy".  You simply must put in the time.

  • dimensional analysis
  • moles
  • stoichiometry
  • gases
  • solutions
  • acids & bases


The second most important factor for determining success in chemistry is knowing how to attack each problem.

Your professor likely teaches this to you in class.  Your textbook is probably well regarded. But no one understands chemistry after hearing it just one time.  Or two times.

  • Your professor does not have time in class to go over all chemistry problems with you.
  • Your text book has problem sets for you to work, but it has no guidance on how to work each problem correctly.


Work the problems in these videos along with our chemistry professor.

  • Our professor demonstrates the shortcuts and strategies to attack each problem.
  • Go back and re-watch each problem being solved until you can solve it on your own.
  • Use these videos along with your own homework - they will be similar.
  • Our professor trains you on the right way to use your calculator so you wont be slowed down during exams.

FAQ

  • Who should take this course?

    High school chemistry students, home schoolers, first year college chem students, high school teachers who suddenly find themselves teaching chemistry in addition to coaching volleyball.

  • Why should I pay for this course, instead of just looking at free YouTube chemistry videos?

    With Joy Lab you get the answers you need by an experienced professional college professor. You will not make the common mistakes other chemistry students make, because we know these mistakes and train you to avoid them. With Joy Lab you get a lot of practice working problems, all in one place, which other free sites cannot provide. Other free sites do not provide calculator guidance. Commit to success. Be at the top of your class!

  • Why is it so expensive? Do you have military/single mother/good student/AAA discounts?

    You get 106 problems clearly explained by an experienced college professor. That’s less than $2.10 a problem. These problems take 7.83 hours to go over. That’s less than $28 an hour. Quality private tutors run $35-$75 an hour. Professional group tutoring sessions run $40-$130 and hour. We are unable to offer discounts. Study this course, and you will succeed without the additional expense of private tutors!

  • Do you guarantee I’ll get an A?

    It all depends on you. So, no, we do not guarantee you’ll earn an A. To succeed in almost anything takes time and practice and effort. If you think chemistry is too hard, and you give up on the first difficult problem, then you will not get an A. If you watch the videos, work every one of these problems (maybe even more than once), and read your text book, and pay attention to your teacher, you will understand chemistry and how to work the problems correctly. That is a good way to ace chemistry! You can do it!

  • If I’m failing chemistry, will your course help me pass?

    This course will help you stay ahead. This course will help keep you from falling behind. But if you are just finding us, and already failing chemistry, it is probably too late. Unless you are willing to work long and hard, and concentrate while watching the videos, and work every one of these problems (maybe even more than once), it will be unlikely you will get your grade out of the F range. But, if you study this course, the next time you take chemistry you will succeed!

  • What calculator do I need?

    Use the calculator that your instructor suggests, or requires. It should have a log key and an exponent key. In these videos we use an Android app called “RealCalc”.

  • What is the best way to use this course?

    Watch all the problems for one series. Next, do the same problems without the video. After doing them all on your own, go back and check your answers with the video.

  • Is that a bird I hear?

    Yes, it’s Chirpy the Cockatiel.

  • What music is playing?

    In order: Cello, wooden recorder, violin, the Vibrafun app, mouth trumpet, and child’s xylophone.

End frustration by mastering strategies that work!

Meet Our Instructor

Our chemistry professor has taught for over three decades. Professor Lehman got his Masters of Science in Chemistry at California Polytechnic State University, Pomona, and his teaching credential at the University of California, Riverside. After spending a few years teaching middle school physical science and high school chemistry, Professor Lehman found his calling at the community college. Many of his students go on to pharmacy school, pharm tech programs, nursing courses, medical school, and forensic science degrees. After teaching for so many years he determined the biggest factor for success in chemistry - working lots and lots of chemistry problems. Professor Lehman developed this eBook and video course to give his students ample practice in all the common questions on any chemistry exam. He knows what skills students need to succeed in first year chemistry.
