Help Rubina start the school year with the right tools

I earned a place in Form 4 at the Lahore Selective School, and I couldn't be prouder. The school has a long list of things I need, including a laptop for the biology course, and a uniform. My mother works two jobs, and the list costs $150, which is more than we have. I love biology and want to become an engineer. A laptop will let me do coursework at home instead of waiting for library hours. I'll take care of everything you give me and I promise to work hard. Items on the list: laptop, uniform, shoes, textbooks, calculator and a bag. Where the $150 goes: • Laptop: $70 • School uniform and shoes: $25 • Textbooks and workbooks: $35 • Calculator, stationery and a school bag: $20 Please ask me anything in the questions section. I'll answer honestly and quickly.
