There are several ways to upgrade your reading comprehension skills, including:

1. Active Reading: Engage actively with the text by taking notes, highlighting important information, and summarizing key ideas. This helps you to retain information better and allows you to refer back to it later.

2. Pre-Reading: Before reading a text, scan it for headings, subheadings, and any other visual aids like graphs or images. This will give you an idea of what the text is about and help you to focus on the most important information.

3. Building Vocabulary: Work on improving your vocabulary. Learning new words and their meanings will help you to better understand the text.

4. Practice, Practice, Practice: The more you read, the better you become at it. So, read regularly, and make it a habit.

5. Ask Questions: Ask yourself questions as you read. What is the author trying to convey? What are the main ideas? This helps to keep you engaged and focused on the text.

6. Identify Main Ideas: Look for the main ideas in each paragraph or section. This helps you to better understand the structure of the text.

7. Summarize: After reading, summarize the main ideas in your own words. This helps to reinforce your understanding of the text.

8. Read Different Types of Texts: Read a variety of texts to expose yourself to different styles of writing and subject matters. This helps you to develop a broader perspective and better comprehension skills.

9. Take Breaks: Taking short breaks while reading can help you to maintain focus and prevent mental fatigue.

Overall, improving your reading comprehension takes time and practice. But with consistent effort and dedication, you can enhance your ability to read and comprehend information more effectively.
