Hi Ramya, try these techniques to improve your reading, speaking, listening, and pronunciation skills in English.
Read Aloud
Read English newspapers, magazines, and articles aloud (not too loudly, just audibly enough for your own ears).
Engage in Word Games
Play crosswords from newspapers or other sources, etc.
Avoid Abbreviations
Avoid using chatting, SMS, texting languages, or abbreviations in writing or speech.
Word Card Technique
Start the word card technique, i.e., choose 5-10 English words, and learn to read, write, pronounce, and understand the meaning of the word before you go to sleep. Try to recall them when you wake up in the morning. If you can't recall, refer to the word card. Maintain these word cards over time to improve your vocabulary. Choose nouns, verbs, adjectives, etc., to learn.
Practice Speaking
Speak with your siblings, colleagues, friends, and strangers in English as much as possible. Accept feedback, corrections, and criticism positively and sportingly with a big smile.
Watch English Movies
Watch quality English movies to enhance your speaking and listening skills. I recommend movies like Ice Age, Shrek, The King's Speech, Pursuit of Happiness, and many more. But I can't list them all here; otherwise, you'll be busy watching movies only! :-D
Record and Review
Read a paragraph or short stories (kindergarten books, short story books, etc.), then record your speech and listen to it. Note your gaps, mistakes, errors, and work on correcting them. Identify the patterns of your mistakes.
Listen to Audiobooks
Listen to audiobooks (not excessively).
Stay focused and passionate about learning. At the same time, take it as a fun activity and enjoy the process.
Don't restrict, pressure, or stress yourself with time limits. Learning is a continuous process. Gradually, word by word, you will grow and learn.
Wishing you all the best.
