This week marked back-to-school for the 1.1 million children in NYC public schools, as well as many private-school counterparts, and the 2015-2016 academic year brings with it no shortage of new systems to master and even new holidays! For example, the DOE's new parent portal we told you about last spring—NYC Schools Account—is now up and running!

Parents will find students' test scores, attendance records and report cards (in 10 languages) in the new portal, which is accessible by computer, tablet or smartphone—a major improvement over its predecessor. You'll need an activation code handed out by your child's school to access the personalized, free account page. All the instructions and required documents can be found on the schools account page.

Returning to the back-to-school routine is challenging enough for most NYC families, but add in finding enriching after-school care to the mix and suddenly we're feeling totally overwhelmed.

Luckily, Mommy Poppins is here to help you sort this all out. Recently we told you about the city's FREE after-school care program that runs 3 to 6pm every school day at recreation centers in Manhattan, the Bronx, Queens and Brooklyn. Now we're rounding up the best NEW after-school class options for NYC kids so you can wish those summer days good-bye a little easier and possibly–maybe?–turn that "school's starting" frown upside down.

The Brooklyn Academy of Music (BAM) is set to embark on a $25 million expansion that will add another building with gallery spaces and a cafe, as well as upgrades like new balcony seating in the Harvey Theater. The former president of the Fort Greene cultural institution and performing arts center told The New York Times the plan is "the last piece of the BAM campus." Construction could begin as soon as this summer, with financing coming from a combination of public and private sources, according to The Wall Street Journal.

In other Brooklyn news, renovations at Prospect Park continue in anticipation of its 150th anniversary in 2016. Six projects are underway by the Prospect Park Alliance, which manages the park, including a restoration of the rose garden and several footpaths such as the one that leads from the zoo to the Zucker Natural Exploration Area (aka, kid play zone), according to DNAinfo.
