Sometimes students, or their parents, look for a math or science tutor by first going online to see what resources are there that can help. If the student has a textbook that accompanies the course, that’s where you should start. Take a look at the first few pages of the textbook to see if it lists an associated website. Oftentimes, just inside the front cover, a textbook lists an associated website that can be a good source of additional learning materials such as charts, tables, video tutorials and other learning aids. Some well-known websites in this category are hosted by Pearson, a large textbook company. A few of their useful URLs are https://www.pearson.com/ca/en.html, https://www.pearsonmylabandmastering.com/northamerica/ and https://www.pearson.com/us/higher-education.html.

Nowadays, some instructors provide the complete course outline and curriculum online, rather than in a paper format.  Enrolled students of these courses are each provided a username and password so they can login and find all of the course material, homework assignments, quizzes, tests and exams at a particular website.

There are some URLs that are dedicated to providing students with online help.  The websites post no-cost or low cost video tutorials to students of Mathematics, Chemistry, Physics and other subjects. Here are some popular websites that provide such resources:

https://www.khanacademy.org/
https://www.video-tutor.net/
