I am writing this answer in order to help anyone who is facing difficulty in scoring 79+ in PTE Academic. This answer would be useful for those non-native speakers who find it tough to express their views and are not absolute fluent in English language.
My first attempt scores were L-59, R-77, S-87, W-62. I failed to get even 65+ in all the sections. After the results were declared I booked the exam in a months time as I thought, the next time I would leave no stone unturned.
