How to Solve NEET Biology Multiple Choice Questions
Aspirants who are preparing for NEET MCQ need to know our 6 tips to get NEET objective questions right. Check out!
1. Carefully read the Question :
This seems obvious, but many candidates make mistakes because they don’t read the statements carefully. And it is necessary to read the whole question, because you may read the beginning of the statement and leave the last sentence blank, and thus, you do not catch what was asked. Read the question and also the alternatives so as not to fall into any pranks. And if you have text, graphics, or tables, pay attention to these elements.
2. Focus on Main keywords / Sentence :
Remember that we talked about reading the Questions to the end, without forgetting the last sentence? This is because the last sentence usually has expressions and keywords that are important for understanding the proposal and may even contain the answer. Therefore, underline the important expressions.
3. Beware of confusing words :
In the same way that there are keywords in the statement, some words are inserted to confuse the NEET candidate. The terms “always”, “never”, “nobody” and “everyone” can be in the wrong alternatives and can lead the student to error if he does not read the question very carefully.
4. Beware of the (“all / Both / none of the alternatives”) Alternatives :
You might come across the famous “all/none of the alternatives” alternatives and variations. This tip is closely related to the previous one because the words “all” and “none” are very catchy and can confuse those who are not sharp in terms of text interpretation.
5. Read the long text of the questions first :
Some questions are based on very long texts, so long that they occupy a good part of the sheet. If you are faced with this situation, read the statement first to understand what is being asked. By doing this, you may already find the answer.
6. Take Mock Test ( Previous year NEET Questions) :
The best way to attest to the effectiveness of the above tips is to put them into practice. You can do this by doing an old and simulated NEET Biology test Series. With this, you also see how prepared you are, in addition to preparing yourself physically and psychologically.
