These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.

  Three controlled edits using an explicit style convention, not all comma rules.

• partial: Place a comma before the coordinating conjunction in a compound sentence, e.g. 'I wanted to go outside, but it was raining'

  Three controlled edits using an explicit style convention, not all comma rules.

• partial: Edit writing to insert missing commas before coordinating conjunctions in compound sentences

  Three controlled edits using an explicit style convention, not all comma rules.
