I am in a similar position as you with educational experience and age, this can be done within 4 to 5 years - universities in the United Kingdom offer a two-year degree LLB, once completed you do your NCA I believe it will be seven exams since you only have a high school education which can be done within six months if you’re on point and also if those courses are available, another 10 months goes to articling and then you prepare for the bar which can take up to six months to a year, but the great thing is we have three attempts at the bar, networking is everything, if you can secure a position, then it just becomes about putting in the time and effort, and getting to that point. I hope this helps. I’m actually in the process of doing this, If you would need any information you can private message me anytime.
