License - A document showing someone is qualified for something. (1-b)

Residency - period of advanced training at a hospital (2-a) 

Prerequisite - Something that must be completed before something else (3-e)

Medical school - An institution for teaching medicine (4-c)

Foundation program -  post-graduate schooling for specialized training (5f) - Но в это есть ошибка. Либо вы сами неправильно написали условие задания, либо в учебнике неверно написано. Так как Foundation program - это программа после 11 класса, наподобие среднего специального, а Post-graduate - это магистратура. Как вариант там может должно было быть pre undergraduate schooling или Post-secondary education schooling, то есть программа подготовки к бакалавриату. 

Entrance examination - A test that must be passed before admittance to an educational institution (6-d)
