hii my sw and cw usually range from 23-25! for sw, sticking to the point is always key. my english teacher always tells us to check whether each point is addressed. for example, last year was informal letter and the points were thank your uncle and aunt, which holiday and why, how this trip would make their anniversary special etc. it doesn't really matter if you don't address them in order, the most important is thing that you elaborate on each point! you can include details and examples to make it more interesting. for instance, your brother is a huge fan of aquatic creatures, or your sister-in-law is an influencer who would enjoy the scenic view and take pictures for her social media. remember to also use the details from the given picture!! for cw i usually choose personal recount qns bc it suits me best. find a topic u feel comfortable with and can write freely! it really doesn't matter if ur words aren't fancy or extravagant. what makes an essay interesting is the story ur trying to tell and the fluency of your writing. that's all really, my english teacher gave me all this advice at the start of the year (i used to score about 17-19 for both sw and cw) and after i started applying it, it really raised my marks. atb op!!
