architecture at ntu - repeating second year

hello

I am looking into transferring over to ntu for second year
I'm a second year student (for architecture)

I am originally from a London uni and its not what I'm looking for in a university and I'm not happy at all with teaching
Last academic year I emailed ntu about transferring for what i need to transfer and i think i have what i need to transfer i do not have the highest alevel grades but do have really good uni credits , but last year didn't go through with it however this academic year I decide to commit to transferring as I'm not happy currently
I do recognise that I will have to repeat second year when I transfer over to ntu

i am just wondering if I am making the right choice my current uni is still quite new and just only got accredited for RIBA, I know that ntu is much better uni in comparison to where i am currently

I want to know if me joining in second year is going to set me back, and how the work load is over there
