Hi Preeti,
It's good to have an attitude to prepare and win. But, when you have no time, do not think about or judge your preparation. You have to go to the exam with a gut feeling you're going to succeed. Then your spontaneity comes to the forefront, and you'll get a good score. It is true, even when you are well prepared. Before the exam never judge your preparation. Just go and kill.

Hi Syeda, please read English aloud daily.
1. Read aloud faster, do not try to understand
2. Take the same paragraph and read aloud to understand.
Your Vocal Chords need to get used to English.
Prefer small articles on some topics & also focus on descriptive materials because descriptive essays invoke your imagination, and once your mind gets involved, everything happens.
3. Please see English Movies. Please give a break for every 20 Minutes. While watching, observe the lip movement of the actors.
If the above 3 points are followed daily, within a short time, your fluency gets improved.

Chandan, nobody is perfect in English, as it is not our native language. Start believing that you can speak English. Do not be conscious of what others think. That's your fear. We get what we focus. Focus on what you want to do (speaking English) & not what you fear. Importantly never think of grammar rules while speaking. Keep reading small stories, as stories are interesting, there are characters that communicate with one another. For a while stay away from New Papers. You can use YouTube to "Learn English through stories ". Just keep on listening without any judgemental mind. As input is happening through reading short stories & YouTube, The output speaking takes care of itself. Erase your judgemental thought process while studying & also while speaking. What the world thinks is its problem, you have to speak English, speak.
