PGCE admission for International applicants (Nigeria)

Hi there,

I'm an international aspirant for the PGCE secondary mathematics course at Chester starting september 2021, I'm domiciled in Nigeria. Here's my question:

(1) Are virtual interviews accepted by the university considering my country is far away. If no, would it be possible to negotiate a favorable time for the face-to-face interview since I would be seeking temporary leave from my present job in Nigeria to fly all the way to UK.

(2) What's the provision for a prior UK classroom observation (2 weeks) because I understand that forms part of the conditions for an offer. Could the school assist me with that upon attending the face-to-face interview and having passed the interview when I arrive in the UK.

PS I have previously studied in the UK, MSc mathematics 2015 university of chester. I also was offered a PGCE place at Liverpool hope university in 2016 while I was in the UK (passed the interview, literacy and numeracy test, plus observed at catholic high school chester). I deferred the PGCE place for family reasons as I had to return to Nigeria.

(3) Is the full tuition fee for PGCE secondary maths at present for international students, and do I get any scholarship as alumnus. I have perused the website but found it a bit confusing. Kindly clarify.

Thanks
