Certification providers normally have extensive web sites that thoroughly explain the content of the exams. In choosing a certification training programme, you should consider how you learn best, the length of the course, location, type of certification offered, reputation of the certification trainer and cost. With all types of courses, students should investigate the reputation and legitimacy of the programme before applying by checking with the certification vendor. The courses are typically offered by independent training organisations, and can vary tremendously in cost and duration. Many certification courses are also offered on-line.
Students can avoid any visa application problems by taking a distance course.
Self-paced training is the least expensive option for exam preparation. Authorised trainers often sell manuals and instruction books that are considered sufficient preparation for certification exams. Because of the more unstructured nature of distance and self-paced training courses, students should carefully consider their study skills and how they learn best before enrolling. The exams that actually grant certification are administered separately from the training courses. Each certification provider links to exam registration information from its web site.
