Training contract application- non law international student

Background: I currently on a graduate visa and work at a law firm based in London. I have an undergraduate law degree from my home country. I am applying for training contracts starting 2028 and have a question regarding the PGDL, SQE and TC commencement timeline.

Firms require non-law students to complete the PGDL prior to starting the SQE - which brings me to my question: if a non law student applying for a 2028 TC is offered one, would they be able to start the TC in time given that they would need to complete the PGDL and SQE? I am just a little confused about the timelines.
