Do I need to be a solicitor to work in a Law Firm in corporate law?

You can do the LPC without the TC and I think the majority of people do. However, in my opinion it is preferable (if possible) to get the TC first and then do the LPC. Some firms will pay for the LPC (and give you some money for living expenses during the LPC year). Chambers Student/Lex100 would be good resources to find out more about the funding situation if you have your eye on any firms/areas.

I just dislike snobbery and elitism. Whether its the office boy, doorman or secretary I respect everyone I work with for what they can do and what they contribute.
