Rule reminder
Common B2 essay errors: (1) using indicative after subjunctive-triggering verbs; (2) using colloquial connectives ('però', 'quindi', 'anche se') instead of formal ones; (3) first-person overuse; (4) informal vocabulary; (5) missing nominalisation. At CILS B2, the examiner assesses both grammatical correctness and stylistic register.
