I can actually relate to this .When I went to enrol at a Sixth form to do A levels , a support worker told me I had very good results for GCSE and should have no problem with the courses I applied for . she gave me my application and encourages me to get it signed by the principal . Whilst in the que , by pure accident , I noticed there was a small note at the back of the application : NOT SURE IF THIS STUDENT CAN HANDLE THESE COURSES.The cultural Marxists subconsciously have very low of expectations of what Somalis can achieve .
That said , the sister should not air out the principal in public . She may need some references from the school and it doesn't look good for future employment , that is , in terms of character reference . You fight your battles with intelligence and composure .
