Science App Review
You need to study for a quiz in chemistry, but you missed classes due to a 2 week vacation, what are you going to do? You can ask friends and family to help you study, but there are more convenient ways to study for you quiz, like using an app.
Khan academy is a great app for learning, it is completely free and has a variety of subjects that you can study on. So if you missed classes, you can go on this website, or download the app on mobile to study what you’ve missed. There are videos and guides to help you, and questions that you can practice. You just have to create an account and you can practice, watch videos, and learn things.
I liked how the app is completely free and easy to use. What I don’t like is how the app on mobile can only watch videos. I used this app in grade 7 for math and I would give this app a 9/10.
