Chemistry exam preparation through mind map

Chemistry is a subject that favors understanding of the theoretical nature. To master the theory, students need a knowledge system in the form of a mind map, review through synthetic questions, mock exams, and illustrations.

The number of theoretical questions usually accounts for 60% of the high school graduation exam questions or illustrative questions in recent years. Therefore, when reviewing, students need to stick to the illustrated exam questions in 2022 to come up with an effective and focused method. Issues to keep in mind include:

1. Basic questions with theoretical content, representing 11th grade knowledge and practical applications:

Have a look at the following two examples:

To solve the synthesis sentences, you should systematize each chapter in the form of a mind map.

Looking at the mind map, it is easy to choose answer D for the question in example 2. This is similar in the following example 3:

2. Metal content knowledge questions and metal outlines make up the majority of inorganic parts

Content knowledge about metals aluminum (Al) and iron (Fe), students need to review carefully, make a table comparing physical properties and chemical properties, the typical reactions of these two elements to make the system theoretical system.

The core knowledge sheet related to Al, Fe and their compounds, is as follows:

Using the above comparison table, let’s try the following two examples:

3. Some math problems can be solved quickly with the formula and the law of conservation of elements

You should practice the above types of exercises in the mock exams to get used to clicking the computer and thinking quickly. Solving mock exams is also an accurate way to measure the level of scores you are accumulating, thereby reviewing your missing knowledge to have a suitable review schedule.
