Sorry I'm just overwhelmed by all that there is on the web regarding the process, also I'm from India and don't know much about how things quite work in this arena!
I understand you may be overwhelmed but if you want to increase your knowledge about the legal industry it is something you need to overcome, there will be hundreds of candidates that have done extensive research and are ready to compete for a vacation scheme/training contract place. If you are feeling overwhelmed now, it isn't going to get any easier the further into the process you reach, so I think you should really perhaps take a break and think things through about whether this is the career/path for you.
I don't think being from India makes any difference. There are many people born and raised in the UK who have no idea about law or the legal profession in general. However, a lot of these people are able to overcome that by conducting research and building up their knowledge base.
Again I don't mean to be blunt, I am just being honest and realistic. There is a wealth of knowledge on the internet that starts from the very basics to the more complex issues. It is up to you to utilise that knowledge to better your understanding.
