So I don't know if this helps but I worked full time as a paralegal and have just secured a TC. Working as a Paralegal is a solid back up plan as whilst the pay is extremely low and it is long hours after two years you can qualify as an NQ you don't actually need a TC under the SQE regime. You just need to choose a solid firm that has a history of converting paralegals to NQs - i.e. AG, Macfarlanes etc.
Getting a paralegal role can be tough too though.
