Before starting your test, write on your erasable notepad these three lines
1. The speaker highlights
2. The professor throws light on
3. The lecturer focuses on
then when re-tell lecture starts, recording will play for around 2 minutes, listen patiently and see the image/graph/table/pie chart (if any), during this time try to note as many keywords spoken in the recording as possible, u will have around 10-12 seconds to prepare yourself with what to speak.
When time starts for recording answer, start with any 1 of 3 lines u have written on your erasable notepad, mention the keywords u have noted down and try to fill in text by yourself to present a story. keep necessary pauses between sentences, but not more then 3 seconds.
Use the three different lines for the different lectures, generally ppl dont get more then 3 re-tell lectures, follow this strategy you shall be clear
