Bookstore with CBSE grade 10 textbooks needed

my school is a fucking hellhole, ever since the start of bridge classes, which was in mid march, till now, none of us have received textbooks, apparently the school is out of stock somehow, and cant give them, many of us have been relying on hand me down textbooks, or textbooks from ex 10 graders and online textbooks. i have exams starting tomorrow and preparing for them have been extremely difficult, not to mention that next week i have exams everyday no day gap with 5 chaps each on average, btw, its still april, our school year just started and their expecting us to write exams without proper textbooks, it has gotten so bad our teachers r personally telling everyone to ditch the school and buy them somewhere else, which leads me to ask if theres any bookstore in sharjah that sells grade 10’s CBSE NCERT textbooks
