In this section you will find the most important documents you need to get general information about the C1 exam:
Even though the Trinity examinations do not have a Use of English or Grammar part, you will be expected to use certain grammar structures, both in the written and oral tasks:
Please note that the language functions are cumulative through the ISE levels.
There are no suggested grammar structures for ISE III.
Candidates are expected to use a broad range of complex structures to express thoughts clearly.
Language functions for ISE III
Developing and justifying an argument
Summarising
Evaluating options, past actions/course of events, different standpoints
Deducing and inferring
Staging
Hypothesising
Indicating understanding of points made by examiner
Establishing common ground/purpose or strategy
And finally, it is really important you take into account the Rating Scales, a rubric that the examiner will use to evaluate your Writings and Speaking / Listening tasks; it will also help you improve your level!
