in yr 8 and 9 i always sucked at english but when it came to SC i studied and got 93 which was a band 6. I got past school papers and studied hard off of them. I also wrote in essay form, if you have no learnt how to write an essay as of yet, teach yourself and you will get good marks, learn puncuation and most of all language technique is one of the major things examiners look for, i wrote a whole list of all techniques and revised them over and over. Even making flash cards may help. Its up to u and how u study tho. But extended response which is usually marked out of 15 or 20 marks which is a large percentage of the paper, make sure you read the question at least 3 times and make sure when you answer the question, you refer back to the question to make sure your answering correctly. I hope i helped! Cheers!
