The Indian Railways recruitment exams for RRB RPF 2018 and RRB Group D 2018 are finally here folks! This is a golden opportunity for all those who wish to have a career with the Indian Railways. This year in 2018, there are 90000 plus vacancies that the Railways Recruitment Board or RRB needs to for the posts of RPF/ALP/Technicians and Group D. While competition is expected to be cut throat, the high number of vacancies will cut down on the pressure to an extent. Another piece of good news is the exam would be held tentatively in the month of September onwards . This gives you, dear aspirants, ample time to make sure your preparation is up to the mark. As the adage goes- Make hay while sun shines. Keeping this mantra in mind, we bring to you this article discussing how to crack one of the most important sections in this exam- General Science. First things first- Let’s have some background on the section. The exam has two Stages and General Science forms a crucial part in both the stages. General Science Questions for RRB ALP and RRB Group D exams include questions from physics, chemistry and life sciences pertaining to Class 9th and 10th. Fortunately, the syllabus is easy and with some systematic planning, can become a very scoring area. The first phase is the most crucial one as a substantial amount of competition would be eliminated here. Although the marks scored in this section do not get added in the final stage, the preparation done at this stage, especially for General Science, would go a long way in helping you prepare for the second stage as well. With proper planning and strategy, it is very much possible to crack RRB Assistant Loco Pilot or RRB Group D exam. This is where we come in - Below are some ways to tackle the General Science section of the exam. So let’s get cracking! Step 1 – Make NCERTs your best friend! If science is your God, NCERTS would be the Bible to reach your God. NCERTs are real gems and their importance cannot be overstated if you want to score high in this section. You skip these at your own peril. They lay down the basics in a lucid manner and give you a solid foundation on which to practice further. The NCERTs requires to be done are of Class 9th and 10th respectively. No guides/ cheat codes can take the place of NCERTS. Starting now, these books should become your constant companion- sleep with these books under your pillow if you have to! Why NCERTs? Well, for one thing, you have already studied these books back in school and this in itself would make the topics familiar. For another, if you look at the first few pages of the NCERTs, you’ll find a list of people who have contributed in authoring these books, with a lot of them being eminent and knowledgeable people. Every line in the NCERTS has been written carefully and adds to your knowledge base. For this reason alone, we strongly recommend you to finish these before you go for any sort of additional material. How to read the NCERTs? Read through each chapter and mark the important topics and headers. For your convenience, we would be providing summaries of all chapters. Keep checking out this space! Try and formulate your own questions. Again, we will be providing free questions on a daily basis on each topic for you to practice extensively! For updates, keep checking this section. The focus should be on basic definitions, formulas, SI units, various theories and laws, devices and their applications etc. To get an idea of the kind of questions being asked, please take a bunch of previous question papers and go through them once. Once you have an idea of the kind of questions asked, it would help you to sort out which issues are important and which ones not so much. Some questions seen in previous year papers are as follows (all MCQs): An electric charge in uniform motion produces what kind of field? What is Piezometer used to measure? Which of the following factors would affect the density of a fluid? The correct unit of angular velocity? What is Boyle's law (definition)? What is the temperature on the surface of the sun? Unit of electrical energy? For more of the previous year’s question papers, click here. Step 2 – Salt Water is a good conductor of electricity! (Application Duh!) Remember how in the movie ‘3 idiots’, Rancho applied theoretical knowledge to get some really cool (although painful) results? This is what this exam expects of you (without the pain of course). The questions asked in the exam would a healthy mix of theory and application of the same. So, knowing what diffusion is is not enough and you should be able to answer why the smell of hot cooked food reaches you even when you’re rooms away from the kitchen while the smell of frozen food does not. Some previous year’s questions: What kind of energy is possessed by a horse running on a level road? What happens to the value of acceleration due to gravity at the poles and equator? Where would the weight of the object be minimum (at poles or at the equator)? Why does a Swimmer find it easier to swim in sea water than in plain water? Why does a stick that has been dipped in a vessel containing water appear bent? As you can see, the level of the questions would be simple enough and the exam merely tries to check if you have really understood what you read in the books. Mugging up is thus, not the right way to go about clearing this exam. Here again, we reiterate the importance of the NCERTs rather than going for any guide/refresher material where the sole intention is to make you a machine- spouting rote learned figures and words. We would be bringing you loads of application based questions soon. Please keep checking this corner! Step 3 – Practice, Practice and Practice! Once you are done with your standard textbooks, it is time to start solving questions to understand your preparation level. Solve the previous years’ papers along with any test series. Remember, to crack this exam (or any), you need to have belief in your own capabilities. This confidence depends on your level of comfort which in turn depends on the quality of practice done. The importance of a test series: Joining a test series is an absolute must. This not only gives you a test-like environment along with other exam-like conditions- time pressure, navigating the system etc, it also prepares you for any kind of surprises that the actual exam may throw at you. Also, with the kind of cut-throat competition where even a single mark may decide the difference between seeing your name in the list and preparing for another year, one cannot afford to leave any stone unturned.

Without a proper analysis, taking even 100 mocks would not really benefit you. The real aim of taking mocks is to understand your weak areas and work on them. This in turn is only possible with a thorough analysis. A typical analysis should involve the following: Mistakes: Try and gauge if the mistakes were made because of faulty understanding of concepts, an inability to apply the concepts or lack of knowledge. Weak areas: Make a list of the areas where maximum mistakes have been committed and go through those chapters again. Improvable areas: These are the areas wherein you have done fairly well but there is scope for improvement, maybe in the form of time taken, method followed etc. Finally, we want to say that cracking this exam takes only three things- a plan, discipline and consistency. Make a plan, create deadlines and then stick to those deadlines.
