Having paid almost £10k for a respected training course to enter this profession, I'm afraid I too take umbrage at the comment that it's "wasting time". It is essential. Invaluable.
I'm now in my fourth month of training. Have planned countless lessons. Had over 30 lesson observations, and had to develop a thick skin. Juggled University assignments with zoom lectures, the academic reading on pedagogy, adaptive practice, understanding SEN and EAL needs, the pastoral care needs, different key stage planning for schemes of work and lessons, marking, learning Assessment Objectives, implementing behaviour management appropriately, completing weekly mentor meeting forms, commentary forms, focused observation forms, forms for the sake of forms.
Learned how to work in lockdown and deliver remote lessons using interactive software, visualisers, whiteboards.
I have 3 kids. I knew it would be insane so strapped myself in, but this year is even more so.
Yes, be humble, be reflective, be honest and be helpful. And yes...resilient. Every one of the trainees at my school have been in tears at some point. But we dust ourselves off and go back for more.
You may of course meet the extremely high demands that gaining a place to study a PGCE requires. It is highly competitive. But don't be thinking you can host a zoom and you're a teacher.
