At first, it was not clear how long repairs would take.
Students finished the last five weeks of their school year at temporary schools across town.
Initially, school officials said it would cost $5M and take six to eight months to complete repairs.
In June, school officials gave ABC11 Eyewitness News a tour of the school and said repairs were going so well they hoped to reopen by August 25. Not only did crews rebuild it faster, they made it better.
The D wing was the damaged the worst. Students will see new classroom equipment, including a flat screen TV and new furniture.
"To see all the work they have done in such a short time, it's amazing," Assistant Principal Antigone Peek said.
Despite the hustle and bustle of the impending school year, she expects Thursday to be a fairly calm first day for students.
"The conversations I have heard from parents, they are prepping the kids and they are excited about coming back," Peek added.
