How do I sync my Learnerator subscription on

You can claim your active Learnerator subscription on and have full access to the same subjects with 3 free attempts per question (ie, it costs no credits to answer each question 3 times in the sync'd subjects).

You can do this from your user Account Settings under the "Sync Learnerator" tab. When you sync an active subscription, it will have the same expiration as on Learnerator.

For example, you have an AP Biology subscription on Learnerator that expires on 7/11/2016, when you sync it on, it will also expire the free attempts on the same date.
