विद्यार्थ्यांनी प्रामाणिकपणे स्वाध्याय सोडवल्यास त्यांचा हा धडा व्यवस्थित तयार होईल ही खात्री. प्रचंड मोठा धडा असल्यामुळे, या धड्याचे स्वाध्याय दोन भागात विभागणे हा एकच पर्याय आहे. पण या धड्याच्या  स्वाध्यायचा एक फायदा असा आहे की हा धडा पुन्हा 12 वी ला आहे. संपूर्ण धड्याचा  व्यवस्थित व्हावा यासाठी छोट्या छोट्या घटकांचा विचार घेऊन स्वाध्याय तयार केला आहे.
