Solving English Reading Comprehension has become an inevitable part of almost every competitive examination. Often students feel they are not efficient in solving Reading Comprehension, because of these three factors.
• Vocabulary in the comprehension.
• Difficulty in understanding the meaning of the questions.
• Time factor.
The question that linger in every aspirant’s mind is “How to improve Reading comprehension?”There are some Reading Comprehension strategies to follow, to get more marks in Reading Comprehension.
First thing is that you don’t need to understand each and every word of the comprehension. At the same time, you should find the gist (summary) of it.Both these points above may appear contradictoryBut the crucial thing is, you need to focus on keywords.
you can choose the “bottom up” approach. That means, read the questions first, so that you have an idea what to look for, in the comprehension.
“I know all the answers, but I didn’t have enough time to solve” examinations not only test your knowledge and skills but your Time Management also. All the three aspects are important,
• Skills (writing, reading)
• Time Management
Divide the stipulated time of the examination, allot certain time to each section, based on your strengths and weaknesses. Practice numerous reading comprehension exercises with the help of a timer. After solving some, you definitely have an idea, about Time Management. /p>
Why you need to improve your vocabulary? Vocabulary means knowledge of words (meaning of words).If you do not have a good vocabulary, you have to stop at every new word in the reading comprehension, and be puzzled.Having a good vocabulary, makes you understand the reading Comprehension much easier.
Do not read the Reading Comprehension like a movie novel. While going through the passage, your three body organs should act in collaboration.
Make a habit of finding valuable keywords quickly and underline those keywords with a pen (If the rules permit, otherwise use a dark pencil).
So, if at all you have to read the Comprehension again you can go only through keywords, and not through all the junk.
When we don’t find an answer to a particular question, we usually tell ourselves “Okay, I will come back to it later”.This may be a good strategy to save time While leaving the difficult questions and solving the easier ones.But before going to another question just do one thing.Take your pencil and make a circle on your choice, which you feel correct at the present moment.
Because when you come back to the question, you would have forgotten the Comprehension itself. So you have to read it again from the beginning. If the time permits, it’s won’t be a problem, but if you don’t have enough time you can choose the earlier marked answer.
It is not unusual for any person to wander somewhere while reading something uninteresting. So, when you find the Comprehension dull, difficult and uninteresting, your eyes run through the sentences, but your mind wanders somewhere else. The result.....you complete reading, but you grasp nothing.
Focus on the content. Don’t let your mind go away from there.
Do not move your lips while reading, it slows you down.If a question asks about a particular line, don’t go back in to the passage and read just that line. A good rule of thumb is to read at least 2 sentences before and after the line in question. This will give you an idea of where the point started and where the author is going with i.
Also try to write your answers in active voice except in case paragraph is about any scientific study.
• First sentence of each paragraph–
The first sentence of a paragraph usually introduces the central thought of the paragraph. It tells you what the paragraph is about. However, in some texts, the first sentence is more of an attention getter. If this case, you'll need to read the first and second sentence of each paragraph. This exercise alone will provide you a very good idea of what the entire chapter is about and the major themes to look for as you read.
Expertise in comprehending paragraph comes through practice, do practice few comprehension using above tips just do not experiment in exams. All the best.

Exams can be a daunting time for even the most diligent of students, not alone for those who are more inclined to procrastinate. Don’t worry the Complete Guide is here. Whether you’ve left it till the last minute or you’re ahead of the game, these revision tips will help to ensure exam success.
What do you need to know? Perhaps the number 1 tip for exam success is knowing what's included on the syllabus. Your teachers will have a basic set of aims and objectives they’re required to ensure their students achieve. Find out what you’re supposed to know and revise accordingly.
We know it sounds obvious, but revising somewhere quiet will help your concentration. It doesn’t need to be anywhere posh, your bedroom or a desk at the library will do. Your study place should have enough light, remember good light increases your productivity –so consider a desk or floor lamp
Don’t just talk it through in the corridor 5 minutes before the exam. You’ll only get yourself into a panic , worrying about what you think you don’t know. Make time for discussion in the weeks and days leading up to the big event Revising in groups can be really useful if you work well with other people; you’ll probably find that you’re better at recalling things if you’ve spent time discussing it with others. Plus it’s more fun, and you can test each other. Also, they say that one of the best ways of learning something is to teach someone else, so if you understand something better than a classmate, teach it to them and you’ll probably find that you both end up better off!
If you are truly coming to your revision at the last minute, I urge you to heed this piece of advice. There is a finite number and combination of questions your department can ask you. Familiarize yourself with these via the magic that is past papers. It's rarely the case that past papers aren’t accessible – google it, go to library. When it comes to essay questions, read between the lines – you've probably seen the question before, its just been worded slightly differently.
An old stalwart when it comes to revision advice, recited since time immemorial – take regular breaks! Don’t take my word for it, scientific research indicates that taking breaks during revision gives the brain a higher chance of remembering what you’ve crammed into it. Try 50 minutes on, 10 minutes off. Do something entirely different for at least a couple of hours in the evening. Watch TV, go for a walk, just generally de-stress, your nerves will appreciate it.
Eating healthy diet during the exam period is a great way of letting everything else take care of itself, so that you can focus on the task at hand. Lots of fruit and veg will give you the minerals, ions and vitamins you need to stave off nasty germs and maintain other bodily functions – need I say more? Replace chips, biscuits with nuts, salads, fresh juices, healthy sandwiches.
Exercise gets the blood flowing. This means more oxygen will reach the brain and help it to function more efficiently. Anything you can do to get the brain working well is surely welcome during the exam period. Plus, it makes for a nice respite from studying.
No, not completely, we know you need your computer to revise. But turn off social media while you’re revising. No one needs to see your selfies with your revision notes if you turn Facebook and Twitter and Instagram off, you’ll find you’re a lot more productive.
Yes, we know we’ve just told you to turn it off, but actually, did you know there are some great apps and websites that can help with revision? Like learner’s hub, khans Academy, cbse.nic.in
Making your revision notes colorful will make it slightly more fun. But it will also help you to recall them when you get into the exam, so go out and invest in some highlighters, some post-it notes and some big sheets of paper. Colors help you to recall facts that have been written down because they engage both sides of your brain.
Reading your notes once isn’t really going to help you all that much. Try reading them a few times and repeating the information to yourself. It’s probably best to do this in the privacy of your own home or you can record your notes and listen them time and again.
It can be really tempting to fuel your revision solely with coffee, tea and energy drinks. But the truth is, caffeine can actually impair your ability to recall information. If you’re struggling for energy during exam season, make sure you take regular breaks and are getting enough sleep at night (about eight hours is normally what the experts recommend).
Use mind maps or mnemonics e.g (VIBGYOR to remember rainbow colours).It improves memory by prioritizing information. Some students find that listening to music while studying help them to be more productive, if that’s your case, keep volume slow and play those songs that you don’t find singing along.
Exams are not the end of the world. And they’re not the most important thing you will ever do, though they might feel like it right now. You’ll work a lot better if you can stay calm about it and maintain a positive attitude.
