Also, 0522 has quite low grade boundaries for Reading, but if you've already got your s&l mark back, as well as your writing coursework, you should work out how many marks you are off your desired grade, and calculate roughly how many you would need to get in the exam. Those who already have high writing and speaking marks are in a favourable position, as you already walk in with a gauranteed C, and can easily push it up to an A or A* with a mark between 30-40.
For example, I have 48/50 in my writing, and for the speaking, which I did before Easter, I'm guessing around 22-21, so I'm estimating that to get 105 overall, I would need 36-37 marks in the exam to just scrape an A*.
