I have to say I am “wowed” by your customer service! These are such excellent preparation books and online practice questions. Even though my son is in the gifted program (class’s syllabus is one grade higher), the practice books and online questions help him prepare and get familiar with the different sections of PARCC. It also helps us determine his weakest areas (he thought he has none), which is wonderful!!! We started purchasing and using the Lumos books last year for his first PARCC test. We did not pay attention, nor noticed there were more online practices until this year!
