When you upgrade your package, you pay the price difference to receive the additional number of resources on top of your current resources. You will also get the full validity period of the higher package from the date of upgrade.
For example, if you upgrade from an OET Express+ to an OET Bronze, you will pay USD$60 and receive 1 writing assessment, 1 tutorial and unlimited Live Classes. You will also get an additional 12 months' access.
To compare packages, see our website.
Please note: because we only have ONE set of course materials and ONE mock test, the upgrade does not come with new course materials or a second mock test.
If you have any questions about the validity of your package, see this article: How long is my package valid for?
If you still have questions you can also email us at firstname.lastname@example.org.
