You can take these Self-Practice tests to apply what you learned from the above lectures. If you are interested in determining how you are doing, you can use ChatGpt, EditGpt, or Google Bard (Gemini) to evaluate your writing for you. Most students mess up their scores in terms of Grammar and Lexical ability, and those AI apps (especially EditGpt) can let you know where you stand in those areas. Also, for each mock test they give you an example which allows you to check on your task achievement. ChatGpt and Google Bard (Gemini) can estimate a IELTS writing score, but first you should ask it to explain the IELTS Task 1 writing rubric and after it does, ask it to approximate a score.  I have found that the AI can be up to 0.5 to 1,0 points off a times, but the more information you give it such as the amount of grammar and lexical errors or the actual graph or chart which can be done in Google Gemini, the more accurate it can score you.

Remember, your purpose of doing these Mock Tests and using the AI is to see your weaknesses. Do not worry about their scoring, the more you improve your weaknesses the higher you will score on the exam. If you do have grammar and lexical weaknesses, go and learn the skills you are missing and use AI to create grammar and lexical practice exercises in those weak areas to improve.
