we are sorry, currently it is not possible to do the exam online, and we don't have any test centers yet in India. We are considering to offer training courses and exams in the US later this year, but we don't have any definite plans or dates yet. It is also vaguely possible that we might start a cooperation with a global certification program with test centers in various countries, but the plans for this are even less specific.
A great possibilty to take part in the exams would be the RCOMM 2012. This is our user conference which will take place August 28-31 in Budapest. Here you can meet a large part of the Rapid-I team in person, and exchange experiences with us and other users. There we also offer training courses and exams. Please find further information on http://rcomm2012.org
