3 year law degree full time and after law school it takes 1-2 years of pupillage. Applying for this is very hard, however if you are accepted the first 6 months is tutoring by a fully qualified barrister and the next 6 months under supervision. During this period you still get paid. You then need to apply for one of the four inns. Whichever inn you choose, you have to stay with it for the rest of your career. By this time, you should be a fully qualified barrister.
Good Luck :D
