How can one escape the severe trials of intense mixing in school when one is unable to keep away from them?

Mixing [between genders] is of two types: permissible and forbidden. If the mixing in the school is permissible and there is no fear of temptation (fitna), then there is no harm upon you. However, if the mixing is forbidden, then you must leave it and search for another school. It is not permissible to remain in it except out of necessity or pressing need, while also being diligent in seeking means of safety from temptations.
