As you keep on practicing, ask God to open your heart to the hidden knowledge, in that way each time when you read the same thing, He will grant His blessings of wisdom to gain more understanding. Use your higher order thinking skills (analysis, synthesis, evaluation and affective )when speaking in order to reflect mature, wise and sensible ideas.
Be prepared mentally, physically and spiritually in order to lower your anxiety level. Think positively to overcome worries, nervousness and uneasy moments. Smile to gain confidence, speak clearly to show your enthusiasm, express well to reveal your passion. Just be prepared for any topics/themes but please don’t depend on them too much as they might be in different colours!
