This page has links to various blog posts which all contain the most common mistakes that Spanish students make when learning English. Each post has a list of mistakes and then it has the solutions below. Sometimes there will be more than one solution, so if you have a different answer, you may still be correct. Try to correct the mistakes yourself before looking at the solutions. All of the mistakes have come from my lessons with Spanish students. These exercises will be really useful if you want to pass the B2 First: FCE (B2 level) or C1 Advanced: CAE (C1 level) exams and get an English language qualification.
