When you hire an online chemistry tutor, you want to ensure that your time and money are well spent. You should look for tutors with at least a bachelor's degree, preferably in chemistry or a related science, a few years of tutoring experience, and extensive chemistry knowledge. If they don't meet one of these criteria, ask about how they compensate for it in their lessons.
Once a candidate meets those three requirements, you can focus on finding the right chemistry tutor. It's important to remember that the best tutor for your friend, neighbor, or sibling may not be the best tutor for you. First, reflect on your experience learning chemistry in a classroom setting. What about your teacher's approach works, and what doesn't? Once you nail down your learning style, you will be able to find a tutor who can cater their teaching approach to your preferred method of learning. Then, think about how you like to be coached, whether it's on the field in a soccer game or playing an instrument. Do you work best with someone who is laidback and easygoing, or do you need a tutor who knows how to be firm and strict when necessary? How you like to learn and how you like to be coached should both be factors you discuss with tutoring candidates.
Lastly, your budget is something that you'll need to consider before hiring a tutor. Sit down and figure out how much money you can spend on tutoring each month. Then, think about how often you plan on working with a chemistry tutor and for how long. If you plan on meeting with a tutor once a week for three months, you may be able to afford to spend a little more than if you are planning on meeting with a tutor twice a week for a full year.
