Are you saying you have a scholarship secured? In which case, bar school will of course be less of a risk.
You can try for pupillage and I wish you a lot of luck, but bear in mind the bar in this country is very concerned with academic results. That’s how it is. Your results are average at best. A 2:2 at undergrad is in fact below what most barristers have in this era, and you didn’t overperform at law school to compensate.
So, by all means give it a go if you have the money, time and mental energy, but with your CV, please be pragmatic and fair to yourself in your expectations. There is no shame in not getting pupillage, it’s crushingly tough. If you have the scholarship, then sure, try. If you don’t, be very honest with yourself. Look at the CVs of junior barristers online — do you measure up?
