We can only see 3 units in the second grade reading classes - how many units do you see and do we have to become a paid member to access all units? Thank you!
Hi! Khan Academy is an NGO, and it's structured around providing free educational resources, so there is no paid membership (but you can donate to the organization). If you are searching for more units, then maybe look at another grade.
