Career planning is of the most crucial in your life, which needs no emphasis. It is important at least for two reasons. First, whether you opt for a career in job or perfect to be on your own, you must appreciate that there is fierce competition for getting a space in the world of work. Remember the old adage, ” Survival of the fittest”. Second , in view of new development primarily triggered off by the information technology (IT) and globalization of the economy, there are now more options than ever before. You will have to look for these options.Remember also that these are days of specialization. When should you begin the career planning? The age that could be considered appropriate for making a start is the age of 14-15 years when you enter the Ninth Class under the 10+2 pattern of education.This is the formative age to shape your career.Much more important reason, however, is that it is after the 10+2 level that a wide variety of courses options are available to choose from.This mean that as the first step you will have to choose from three streams viz., science , arts and humanities, and commerce and the appropriate combination of subjects, when you enter the 10+2 level. To a great extent, this choice would determine the course options available to you after the 10 +2 level. For example, if you want to take up engineering degree course, you should not only join science stream but should also opt for the combination comprising Physics, Chemistry and Mathematics. Before you enter the 10+2 stage, you may like to consider which syllabus provides wider options.As you are aware, there are three Secondary Boards viz., The Central Board of Secondary Education(CBSE) and Council for the Indian School Certificate Examination(ICSE) and the State Boards, each having its own syllabus. While the CBSE and ICSE syllabuses permit combining biology and mathematics, not all the State Boards provide similar opportunity. For example, the Andhra Pradesh Board of Intermediate Education (equivalent to Higher Secondary Board) does not. It limits your option, because at this stage itself you will have to decide whether you want to join the engineering college or medical and agricultural colleges. However , as the number of CBSE and ICSE affilated schools in States is small, you may have to opt for the State Board syllabus. Before you embark upon planning your career you may to consider two issues: 1. Do you need an immediate job because of some adverse family circumstances? 2. Is your family financially sound enough to pay for your professional education? If you need a job, say after you complete the secondary Neuron(IPA: also known as neurons and nerve cells) are electrically excitable cell in the nervous system that process and transmit information. Neurons are the core components of the brain and spinal cord in vertebrates and ventral nerve cord in invertebrates, and peripheral nerves. In animals, the brain is the control center of the central nervous system, responsible for behavior. In mammals, the brain is located in the head, protected by the skull and close to the primary sensory apparatus of vision, hearing, equilibrioception (balance), sense of taste, and olfaction (smell). While all vertebrates have a brain, most invertebrates have either a centralized brain or collections of individual ganglia. Some animals such as cnidarians and echinoderms do not have a centralized brain, instead have a decentralized nervous system, while animals such as sponges lack both a brain and nervous system entirely. Brains can be extremely complex.For example, the human brain contains roughly 100 billion neurons, each linked to as many as 10,000 other neurons.
