My daughter was at Cambridge for 4 years: three years for her BA at one 'unfashionable' college and one year for her MPhil at another 'even more unfashionable' college. She was pooled to her first college, made many great friends (students and Dons alike) loved the place and got a First. She was also 'pooled' to her second college and they were great during the worst of the Covid emergency, which took up her whole Masters year. Both colleges have been very supportive since.
You knew the rules and process before you applied and, actually, they have been positively applied to you. You have done well so please now forget everything else, enjoy yourself and maybe, just maybe, do some academic prep which will help you make a strong start.
Several of my daughter's friends were at Homerton. All loved their college, nearly all got Firsts and distinctions on their MPhils and all are now doing well in a range of professions.
