Thank you for your post!
If ACCT C102 uses the same textbook+edition as ACCT C101, and ACCT C101 has been marked finished by your instructor, then your account will automatically allow you to access ACCT C102. However, if the textbook has changed then you will need to purchase a new code. If only the edition has changed, please let us know and we will look into providing you with a new code.
You will not re-enter the code you previously used for ACCT C101. Instead, locate the ACCT C102 class section and attempt to login with your existing account.
Please let me know if you have any questions. Have a Happy New Year!
I don't have that book at all.
