20975: The report highlights familiar remedies: decentralize bureaucracies, make schools more accountable, break up large schools into smaller units and build partnerships with parents, colleges and business.
20976:                                                                                                                                  It also urges greater equity in state funding of local school districts.
20977:                                               It proposes more Federal funding for a range of programs like early childhood nutrition and incentives for closer ties between colleges and ghetto schools.

   1:                                                     So there is no way for me to plug it in here in the US unless I go by a converter.

3145:                                                                                                               Appetite instantly gone.

3147:                                            The whole experience was underwhelming, and I think we'll just go to Ninja Sushi next time.
3148: Then, as if I hadn't wasted enough of my life there, they poured salt in the wound by drawing out the time it took to bring the check.
