Where I am, those kids with deeper issues preventing them to learn as quick as others often have to repeat a class, fail again and then get send to special schools. In theory they should get more appropriate help there, but normally there is not more funding in these special schools and it's even harder because all of the pupils have bigger learning deficiencies. So often these kids are left behind. The only solution that gives every kid an equal opportunity would mean a massive increase of funding of schools and teachers. But even if that would happen, we currently do not have enough well educated teachers and the job is also not very popular due to high stress and low pay and new teachers take many years to be available...
