Hello Students. Welcome to Mystery In Chemistry’s Tips & Tricks series. Understanding chemistry and scoring high in exams are two different things and hence require different set of skills. Let us learn some tips and tricks to help you score 100/100 in chemistry. So the 11th tip is simply, Focus & Concentrate on what you know during the examination. You will invariably come across a question that completely stumps you out and can easily derail your time management. It can be a Multiple Choice Question, a numerical problem, a short or long answer question, anything - that you just can not deal with right now. The only way is to move on … So Focus on what you know during the examination. But How? Students have all kinds of doubts and uncertainties on the exam day. Almost everyone feels some kind of tension, or nervousness that day. But it is important to leave all that outside the exam room.

Hello Students. Welcome to Mystery In Chemistry’s Tips & Tricks series. Understanding chemistry and scoring high in exams are two different things and hence require different set of skills. Let us learn the 10th tip to help you score 100/100 in chemistry. So here is the 10th tip. Make the most of reading time before Examination starts. Most Board examinations provide reading time before writing begins. During reading time, students are permitted to read the exam paper but not use pen or pencils, nor mark the paper in any way. Some students find reading time frustrating. They just want to start writing at the earliest. But a planned and systematic approach to reading time will help you tackle the exam paper more efficiently and effectively – giving you a significant advantage provided - you use it properly. What to do during reading time! Let's go through the first moments of the exam. You need a strategy! First, calm your nerves and settle into the groove of the thi...

Hello Students. Welcome to Mystery In Chemistry’s Tips & Tricks series. Understanding chemistry and scoring high in exams are two different things and hence require different set of skills . Let us learn some tips to help you score 100/100 in chemistry. So here is the 9th tip - A picture is worth a thousand words. So Start With A Diagram While Answering Descriptive Questions. The best way to answer a descriptive question is clearly draw the diagram related to the question first. It can be a graph, an equation or even a free hand sketch. Then start writing looking at the diagram. Your thoughts will be precise and the answer will require less time to be composed. Moreover, it will be easy for the examiner to understand that whatever you have written is correct, because the diagram is correct. Suppose the question is - Account for the following : Although Fluorine has less negative electron gain enthalpy yet F2 is strong oxidizing agent. Why? (3 Marks) Now for this question...

  Hello Students. Welcome to Mystery In Chemistry’s Tips & Tricks series. Understanding chemistry and scoring high in exams are two different things and hence require different set of skills. Let us learn the next tip to help you score 100/100 in chemistry. Here is the 8th tip - Use Chemical Equations To Solve Organic Questions - Concisely. Questions on organic chemistry range from conversion, complete the reaction, what happens when, write the mechanism, explain the given Name reaction or reasoning. The common trick across these different type of questions is essentially use the chemical equation in your answer. Now, let us take an example. Suppose the question is - How do you convert the following : (i) Phenol to Anisole (ii) Ethanal to Propan-2-ol For all organic chemistry questions you need to be very clear about structural formula, name of the compound and chemical equations. It is because 90% of the answer in organic chemistry can be expressed in equations. Even the exam...

Hello Students. Welcome to Mystery In Chemistry’s Tips & Tricks series. Understanding chemistry and scoring high in exams are two different things and hence require different set of skills. Let us learn some tips and tricks to help you score 100/100 in chemistry. So here is the 7th tip - Use tabular format to answer questions where necessary. Many questions warrant an answer in tabular format. For example, questions around listing out differences or asking you to compare two things, can be answered briefly and clearly in a tabular format. Here, is one such question - Write two differences between an ideal solution and a non-ideal solution. It is 2 marks question. So you have 5 minutes to answer it. You should be able to recall the following points - raoult’s law, mole fraction, ideal solution, non ideal solution, negative and positive deviation, ΔHmix, ΔVmix and partial pressure. However, you must realize that answering the question in descriptive manner is not going to wo...

Hello Students. Welcome to Mystery In Chemistry’s Tips & Tricks series. Understanding chemistry and scoring high in exams are two different things and hence require different set of skills. Let us learn the next tip to help you score 100/100 in chemistry. So here is the 6th tip - Go step-by-step while solving numerical problems. Here is a 3 marks numerical problem.  The decomposition of NH3 on platinum surface is zero order reaction. If rate constant (k) is 4 x 10–3 Ms–1, how long will it take to reduce the initial concentration of NH3 from 0.1 M to 0.064 M.                       (3 Marks) You may recall from our previously discussed formula that you should not take more than 7 minutes for a 3 marks question. Very often students know the answer but do silly mistake while omitting few steps.  Always go step-by-step. Because you are getting marks not only for the correct answer but also for each step.   First s...

Let us learn some tips and tricks to help you score 100/100 in chemistry. So the 5th tip is all about time management. As the saying goes - Manage your time before time manages you. It is common to see students spend a lot of time on simple 1 mark questions and be left with very little time at the end for solving lengthy 10 mark questions. As a result they miss those last questions altogether, in spite of knowing the answers. So the need fo the hour is to Manage your time effectively right from the beginning of the examination. Let us be real. Exams are pretty awful for a whole bunch of reasons but one of the reasons that probably tops the list is - the Time crunch. You might have prepared well for the exam.
