1) In Russia, schooling starts at 6-7 years old, and ends at 16-17 years old. They study in England from 5 to 18 years old, the last 2 years of schooling are equivalent to the first courses of Russian universities.
2) Education in Russia is carried out in large classes (25-30 people), as a result, not all students receive enough attention from teachers. In English private schools, as a rule, small classes (15 - 20 people), which provides a more individual approach.
3) In the UK, a large selection of schools that accept only boys or girls for training. If parents are looking for a separate education school for their child, it makes sense to pay attention to English guesthouses.
4) In England, in high school (A-levels, IB), students study only those subjects that they themselves have chosen. In Russia, some subjects taught in graduation classes are mandatory.
5) In the English education system in high school (A-levels, IB), school subjects are studied in more depth. English students have the opportunity to choose their subjects of interest as early as 14 years, which is a prerequisite for early definition of goals and plans for the future. Education in high school involves a lot of independent work (information retrieval, analysis, own ideas and conclusions).
6) In the UK, the interaction between teachers and students is very different from the Russian model. British teachers treat students with respect and tact. The learning process is a dialogue rather than just the transfer of knowledge and materials.
