my ielts exam
When you deal with IELTS, the first thing the assessor sees is your layout, which shows whole of your essay. If the layout is difficult to read, which is let's say: no spaces between paragraphs, then he/she immediately knows your writing needs more work to read.
Hence, I suggest you to leave one space every time you open a new paragraph.
Allocate your time and effort in approximately 4 to 5 hours every day to read as many authentic English texts/ samples of IELTS writings from this site (EF) as you can to improve your writing skills. Reading texts not only gives you some new ideas about different topics, but it also improves your vocab and grammar
