What’s the best way to study for a 12U chemistry exam
A
Avneet D
InstructorHey,
That's a great question :)
I think the best strategy would be to try to make good notes for your class first. If your teacher already provides you with powerpoint slides you can add additional notes to the margins of the notes during class to help you understand the concept. Then either in class, or when you're reviewing, you can highlight key concepts.
When you do your homework, circle questions you found difficult or got wrong on the first try. When you're reviewing for an exam, you can spend some time reviewing the questions you circled. This will help you save time and study effectively. By reviewing these specific questions, you won't make the same mistakes on the exam!
After learning a concept in class, you can visit this website to watch the videos if you had trouble understanding a concept and/or want more practice. This is a great resource to use weekly and before the exam :). In this course, at the end of each chapter, I've also included a summary sheet that you can use to check and see if you understand all of the main concepts in the chapter. This sheet is a great resource to use before tests! If you forgot something, you can then go back, check out the related videos, and try the practice :)
Enjoy the course!

Why do you enjoy chemistry?
A
Avneet D
InstructorHi, welcome to the course!
That's a great question.
in high school I found it hard to understand chemistry's applications to our everyday life, but after learning organic chemistry in university, I realized that chemistry literally makes up everything around us and us! We have chemicals in our brain called neutransmitters that can alter our mood or functions, and chemistry makes up everything from the food we eat, to the clothes we wear, to the materials used to build our homes. There are so many applications of chemistry and the world is so interesting when you think of it from a chemistry perspective :)
In university, I was personally very interested in learning about diseases so I studied pathology and was very surprised to see how important chemistry is when it comes to diseases as well. Schizophrenia, parkinson's disease, Alzheimer's disease, and depression are all examples of conditions where the neutrotransmitter balance in the brain is off. Scientists can take this information and apply that to drugs to try to treat these diseases. I learned about pharmacology as well (drugs and how they work) and found that extremely interesting too!
Possibilities with chemistry are endless :) Have fun with the course!

For finding molar concentration stuff (eg volume or concentration) in a dilution, does the identity of the substance matter?
For example, in the question "What is the mass of solute required to make 1.0x10^2 ml of a 10.0M solution of LiCl" would the identity of the compound matter? If it were to be NaCl or another compound, would the mass of solute remain the same?
S
Silvija S
InstructorThat's a great question!
The identity of the compound does matter for any calculation involving molar mass, with units of g/mol, as every compound has a different molar mass!

Is grade 12 chemistry similar to university chemistry?
A
Avneet D
InstructorHi, welcome to the course :)
University chemistry in first year usually does cover a lot of the same concepts as grade 12 chemistry. In university, you'll also build on what you learned in high school and learn entirely new units as well :)

Is this class like highschool
J
Jessica Y
InstructorIt covers the topics that are commonly taught in a high school chemistry class. The theory videos and examples break the concepts down into small bite-size pieces, and the practice questions with video solutions give you extra practice to master these skills

Will chemistry be taught differently for each program in university you choose?
A
Avneet D
InstructorHi,
In first year university, all of the students in different programs that require chemistry will usually take the same course as long as they took grade 12 chemistry in high school :)

How did you get connected with Wize
A
Avneet D
InstructorHi,
I really enjoyed my courses in university and found I liked teaching too. I volunteered at places where I was able to teach and found that helped me get a lot better at it. Then I gained more teaching experience teaching for MCAT prep courses. Eventually I applied to work at Wize because they needed help with preparing students for their university chemistry exams :) It ended up being a good fit for me and here I am a few years later!

Is there a big change in the type of work from grade 11 chem to grade 12 chem?
A
Avneet D
InstructorHi, good question.
The concepts you learned in grade 11 will still come in handy, but a lot of the grade 12 units are brand new!

What are some easy ways to remember how to name organic chemistry molecules?
A
Avneet D
InstructorHey,
In the first chapter, I go over a lot of details on naming organic chemistry molecules. In each section, I go into detail on each functional group and how to name molecules with those functional groups. There are "cheatsheets" for each functional group to help you remember how to name them!

Is chemistry as a major good for applying to Mes school?
A
Avneet D
InstructorHey,
Something I didn't know when I was in high school was that if you want to be a doctor or think you might want to, you actually don't need to have a specific major or degree to prepare you for medical school! Having a certain degree doesn't give you any advantage over other students when applying to medical school. That means that you can actually study whatever you like in university! You can take electives to explore and figure out what you like as well.
If you think you might want to be a doctor, you just have to ensure you have certain prerequisites for med school, which includes biology in first year (both semesters I believe), chemistry in first year (both semesters), and physics. As long as you have those science courses, you can take whatever other courses you like!
My major was in pathology (the study of disease) and I got to take a wide variety of courses (pharmacology-drugs, physiology-study of the function of the human body and organs, etc, psychology, chemistry, biology, math, & pathology) :)

How does University chemistry differ from High school chemistry?
A
Avneet D
InstructorHi.
Welcome to the course :) University chemistry builds off of all the concepts you learn in high school chemistry. Each of the units you cover in high school are covered again in first year university chemistry. In university, the material is just covered a lot quicker and they add extra details. Having a good foundation and understanding of high school chemistry will definitely help a lot in university!
For a lot of my courses in first year university, especially in the first semester of first year, I found that there was a lot of overlap between high school and university courses.

Is chemistry key when becoming a dietician? How is a career as a dietician?
A
Avneet D
InstructorHi,
I know that chemistry is required to become a dietician or nutritionist. Certain colleges and universities even have programs where you can major in nutrition! You will learn about the molecules that make up food, how food is broken down by the body, how our bodies can take up the nutrients, the energy that food provides us, and a lot more!
You most likely will only take chemistry in first year university for that program. You will also take physiology courses (studies the function of the human body and organs) and gain an understanding of biochemistry (looks at how the molecules of food are stored in our bodies and how we convert food into energy)!

Would you say university chemistry requires more memorization compared to high school chemistry?
A
Avneet D
InstructorHmm that's a good question.
There isn't too much memorization in university chemistry. I think students find it hard because it is a lot of content taught in a shorter period of time.
To do well, you'll need to keep up with your classes and homework. With more practice, you'll get a really good grasp of all of the problems. :)

uhmm hi miss, i was wondering if we do alot of chem in nursing
A
Avneet D
InstructorHi,
Yes, chemistry is important for nursing. Nurses have to take chemistry in their programs. You will most likely focus on possible reactions between various drugs (pharmacology) or even possible reactions between food and drugs. Having an understanding of chemistry and chemical reactions will help you understand more difficult concepts covered in the program :)

How does chemistry transfer to engineering (computer engineering / software engineering) ?
A
Avneet D
InstructorHi,
That's an interesting question. Chemistry is usually a requirement in university for these programs. Aside from that, you probably won't be using a ton of chemistry knowledge in these programs. For some computer engineers that are specifically desiging computers, chips. and/or computer components, chemistry comes into play more because the computer engineers need to try to make the controlled flow of electrons inside a computer faster and as efficient as possible.

what are some of the most important key concepts in this course?
A
Avneet D
InstructorHey, great question :)
At the end of each chapter in this course, you'll find a "Summary checklist". I've put this together to include the key concepts you should have mastered by the time you are finished going through the chapter.
While studying for a test, you can go through the checklist to ensure you know what each point is referring to and how to solve those types of problems! If you're not sure what a topic is, you can go back to the course and review that topic.
Best of luck!! Let me know if you have any other questions :)
