Lack of appropriate depth in the understanding of concepts would generally result in low score which is not good enough to secure a high rank. This applies specifically to aspirants of JEE/NEET aiming for admission in a college of their choice. Many students experience far less reward in terms of their rank for the effort they had put in for the examination. Our experience tells us that in a lot of cases this is due to gaps in the understanding of introductory concepts taught in Class X and their advanced applications in Class XI which affects students’ performance in the examination. With student success in mind, authors have put together topics and appropriate examples to help students connect the dots. In essence, this set of three books is aimed at helping students avoid the common preparation pitfalls by bridging the learning in Class X and XI for better progress and readiness for JEE/NEET.
