Hey
"Nobody wants to lose. Everybody is here to win. But only the person who has the willingness to 'prepare to win', wins."
You need to take care one thing, GD is not a selection round, GD is basically rejection round. You need to focus on few points for GD preparation which is listed below:
1. Get rid of speaking fear: You need to practice with your friends, take mock group discussions in class, If you can command over fear, then you will be able to outperform as compared to other candidates.
2. Have faith in your abilities: A battle is half won if you are mentally ready for it, and if you prepare hard, that will give you necessary confidence to win
3. Read Newspaper: As simple as it sounds, but most important for vocabulary building, content making, also to stay updated around the world.
4. Content is king: The quality of your content will depend on the ability to think at your feet. You need to present surveys, analysis to score well in GD.
5. Listening and Presentation, a must: You need to be a good listener, so that you can catch up with points of other member and carry on GD, also your content should be presented with "soft" words.
For Personal Interviews, you need to know about yourself in complete detail. Some of the tips are:
1. Stick to precise and honest answers, as you will be caught for fake and creamy answers. You need to present the truth about yourself but molded with soft words.
2. Formulate answers to questions which can be asked in PI, this will help you in upcoming interviews.
3. Also, all the questions will be asked from your answers only. So, present your answers in such a way that you are master in that area.
4. Questions can be asked from Work-Experience, business world, general awareness, tackling a situation.
So, all you need is to practice well. As it will help you in upcoming interviews also.
All the Best!
