Many of the fundamental concepts of chemistry can be learned through university websites that provide learning materials free. [3] X Research source You can also find helpful guidebooks, such as SparkNotes or the “For Dummies” books, at your local bookstore. Write concepts out by hand. Studies have shown that when you write by hand you’re more likely to remember the concepts. [4] X Research source
The University of Liverpool runs a website called ChemTube 3D that has free interactive animations and structures for many chemistry concepts. It will even run on your phone or tablet. [8] X Research source
If you’re still having trouble, try to find a tutor or a friend who’s better at chemistry to help you out. You can also ask your teacher or professor. Write down any questions you think of while reading the textbook and ask your teacher or professor the next day.
What system or change does this formula describe? What do the variables mean and what are their units? (Units can help you to understand what you need to do next. ) When and how should this formula be applied? What is the significance?
Just like athletes practice their sport every day to get better, you have to do the same to learn and get better at chemistry. Chemistry concepts build on each other, so if you do not fully understand a concept, then you won’t understand other concepts that build on that concept.
If you don’t understand how to do the homework, arrange to meet with your professor during their office hours for help.
If you must miss a class, arrange to get the notes from someone in attendance that day. Exchange numbers or email addresses with a couple of classmates early in the semester to ensure that you will have someone to contact. Also, make sure to email your professor to let them know you will not be there that day. They might be willing to let you take any in-class quizzes during their office hours. You can also visit them during their office hours to ask questions and get additional help if needed.
Your professor may also give you a copy of an old exam to look at. This will help you determine the type of questions you may see on your exams, but it won’t tell you exactly which specific questions you’ll have to answer.
