When do you recommend to take the ADX test? Before class starts or within the first two weeks?

95-100% of a typical class takes the ADX test during the first 3-4 weeks of the class while at Sheffield’s 5-week course.

The earlier the better, whether before the class starts (very rare and absolutely not required) or during the first couple of weeks. Just don’t get discouraged with trying to learn some of the numerical problems – we’ll show you many of the “calculation” type problems in electronic workshops that you will have access to once enrolled in the course, even before you arrive.

We recommend applying for the course early enough to gain online access and “pre-study” for a few weeks before your first day of class.

The majority of students end up taking the test during the 3rd or 4th week of the course.
