If you attested for the 90 days in 2011, then you have to to attest for the whole year of 2012. They will start accepting attestations starting Jan. 1, 2013 for the year of 2012.
Basically, yes. You can't even start the attestation until this year ends. My guess they will be more strict for second year people. Year 1 was just about seeing if you had the ability (attestation). Year 2 will be about performance.
