How we build your confidence

• This training course will utilise a variety of proven adult learning techniques to ensure maximum understanding, comprehension and retention of the information presented.
• The sessions will be given in real time through live webinars (instructor-led training); some exercises will be executed during the sessions, others will be done as homework.
• The daily sessions will be highly interactive and participative. This involves regular discussions of applications as well as hands-on exercises that will be solved manually and/or using Microsoft Excel.
