How to Get Centum in Exams

Centum study from zeal study shares you the tips to score centum in your exams.There are a number of tricks and practices which can significantly improve your chances of scoring high on a test. This article will help you in studying, analyzing and solving exam questions
Pay attention in your classes and concentrate. The best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class! Letting your mind wander or not showing up at all are both likely to make you miss out on key information that will later appear on tests.
Take good notes:
. This is important if you want to have an easier time studying later. Not only will writing the information down as you learn it help you in absorbing the information and paying attention, but you'll have a reference for when you go to study later
Do your homework. Homework, such as assignments and at-home reading are where you will find the rest of the information that will be on tests, so doing this homework is important. Schedule time and set aside a quiet place just for homework to help beat the procrastination blues.
Use mnemonics and other tricks. Various memory tricks really can be useful for remembering certain things like numbers, categories, and lists. Just make sure that you learn them correctly and don't mix them up
Mnemonics are phrases :
which can help you remember the order of certain things. For example, "Katy Perry Came Over For Great Songs" is a great way to remember the biological classifications (Kingdom, Phylum, Class, Order, Family, Genus, Species).
Do practice tests. Ask your teacher or go online and print a few practice tests. Taking a practice test will help you figure out how much information you actually know vs how much information you think you know. Knowing your weak spots before a test is crucial
Study frequently. Studying hard for only a few hours the night before the test isn't going to help ensure perfect scores. If you really want to ace those exams, study old and new material every day, or at least several times a week. This will make test-taking a breeze.
Take study breaks:
 When you study, make sure you take a 5-10 minute break after every 30 minutes of study. This will help keep your brain from getting overloaded and give it more time to absorb the information.
On study breaks, try not to fill your brain with more information, even if that information is more about your favorite celebrity's latest concert rather than Winston Churchill's foreign policy.
Study according to a learning style that fits the subject. Certain subjects are easier to understand when studied using a style that connects to the nature of the subject. For instance, if you're studying literature, you'll need visual reading and writing activities. If you're studying music, you'll need auditory resources.
Learning styles:
 as conventionally understood, are somewhat controversial. Many academic studies suggest that learners develop subjective preferences for studying material, but these styles don't necessarily mean they learn better through these styles.
Nevertheless, the idea of learning styles still persists even in academic circles. If a subjective preference for a certain learning style helps motivate you to study, you can still try it.
Take advantage of sense memory:
 Your brain is pretty good at associating smells or sounds with ideas or memories. You should take advantage of this! While you're studying, wear some unusual cologne or perfume (with a smell you don't usually encounter) and then expose yourself to that smell again right before or during a test
Listen to music . Your teacher probably won't let you have headphones during a test, but you should at least listen to music, specifically classical music, right before taking a test. Studies have proven that exposure to certain types of music right before rigorous mental activity can really help, by waking up your brain and increasing your awareness

Carbon and its Compounds

Two or more elements combine to form compound. There are two types of compounds- Organic Compound and Inorganic Compounds. Organic compounds are the one which are made up of carbon and hydrogen.
Covalent Bond
The bond formed by sharing a pair of electrons between two atoms are known as Covalent Bond. Carbon forms covalent bond. Carbon exists in two forms- as free state and as combined state. Free form of carbon is found in graphite, diamond and fullerene. In combined state, carbon exists as Carbon-dioxide, Glucose, Sugar etc.
Allotropes of Carbon
Different forms of an element that has same chemical properties but different physical properties are known as Allotropes. There are three allotropes of carbon- diamond, graphite and fullerene.
Diamond
Diamond exits as three-dimensional network with strong carbon-carbon covalent bonds. Diamond is hard in nature with high melting point. It shines in presence of light and it is a bad conductor of electricity. The most common use of diamond is in making jewellery. It is also used in cutting and drilling tools.
Graphite
Graphite is made from weak van der wall forces. Each carbon atom is bonded with other three carbon atoms in order to form hexagonal rings. It serves as good conductor of heat and electricity. It is used as dry lubricant for machine parts as well as it is used in lead pencils.
Fullerene
It is a hollow cage which exits in the form of sphere. Its structure is similar to fullerene. But along with hexagonal rings, sometimes pentagonal or heptagonal rings are also present.
Structure of fullerene
Two Important Properties of Carbon
Catenation and tetravalency are the two important properties of carbon. Catenation is a property of carbon by which carbon atoms can link one another via covalent bond and can form long chains, closed ring or branched chains etc. Carbon atoms can be linked by single, double or triple bonds. Carbon has a valency of 4 due to which it is known to have tetravalency. Due to this one carbon atom can bond with other 4 carbon atoms, with other atoms also such as Oxygen, Nitrogen etc.
Hydrocarbons
Compounds which are made up of carbon and hydrogen they are known as Hydrocarbons. There are two types of hydrocarbons found - Saturated Hydrocarbons and Unsaturated Hydrocarbons. Saturated Hydrocarbons consist of single bonds between the carbon atoms. For Example, Alkanes. Alkanes are saturated hydrocarbons represented by a formula, CnH2n+2
.Unsaturated Hydrocarbons are the one with double or triple bonds between the carbon atoms. For Example, Alkenes and Alkynes. Alkenes are represented as CnH2n whereas alkynes are represented as CnH2n-2.
