Answer 3

SoloLearn gives one lesson practice per course if you are not subscribed to PRO (costs real money).
So, you have two variants: pay money (after 14 days of free trial if yearly subscription) and receive extra features (including all the practice) or do not pay and use only free features. If you would choose to use only free trial for PRO, do not forget to unsubscribe at least 24 hours before free trial expires and keep in mind that SoloLearn, as well as other services, gives free trial only once.

If you are on Android with Google Play Store as (one of) main, any real-money purchases in apps can be done with Google Pay (one of Google Play Services).
