How a C1 grammar quiz helps you prepare

Preparing for a C1 English exam means drilling structures like inversion, mixed conditionals and the subjunctive until they come out correctly under time pressure. A C1 grammar quiz built from your own course notes or worksheets targets the points your teacher actually covered instead of generic material. DeckOwl reads the file and writes questions with explanations, so each mistake teaches you the rule behind it.

Multiple-choice, true/false and short-answer questions
Explanations for every answer, so mistakes become lessons
Free plan: 3 generations per month, studied in the browser
Paid plans add PDF and DOCX export; Pro adds QTI 2.1 and Moodle XML

Example C1 grammar quiz questions

Which is correct? (a) Rarely I have seen this. (b) Rarely have I seen this.(b) Rarely have I seen this. After a negative adverbial such as rarely, the auxiliary verb moves before the subject.

Complete the sentence: If I had studied harder last year, I ___ a doctor now.would be. This is a mixed conditional: a past condition in the if-clause and a present result in the main clause.

Complete the sentence: It is essential that he ___ the form by Friday.submit. After expressions like essential that, formal English uses the base form of the verb, which is the subjunctive.

Complete the sentence: Had it not been for the rain, we ___ won the match.would have. The inverted if-clause describes a past condition, so the main clause uses would have plus the past participle.

Choose the correct word: ___ the delay, the project finished on time. (despite / although)Despite. It is followed by a noun phrase here, while although would need a full clause such as although there was a delay.
