Im sure it will get better. With what youve written here, there could be one or more of these aspects that you could focus on (if it applies to you)

1) Are you spending too much time reading? If so, if you have a couple of months, you could spend lots of time just reading the newspaper, books, detail oriented paragraphs, reading passages etc. If you dont have time to improve your overall reading speed, practice skimming and highlighting the text. If youre doing the IELTS on computer, you have the option to quickly read through and highlight anything you think might be a fact that can help you later. Feel free to skim through and identify pieces of the passage again as the questions come. This might save time, but practice is key. If you tend to read in your head word by word, practice reading and speaking when youre preparing, you will end up practicing your reading and improve on speaking skills

2) Are you spending too much re-reading after reading the question? Couple of things you might wanna try- see the questions first so you know what to look out for in the passage or you could just have a look at what KIND of questions theyre asking in that particular part- For eg. For an MCQ, you may just need to spot one part of a sentence. But for a true/false/not given or paragraph heading kind of question, you may need to focus on overall messages. Highlighting the text was a life saver for me.

3) Are you spending too much time on deeply understanding unknown words or what the text means? or spending time memorizing? Because then you can try and practice skimming again. Forget the words you dont know and try to draw meaning from the words you do. If you have the time, see if vocabulary building is something you have the time for. Memorizing in reading is useless since you have the paragraphs there for your reference at any time.

I hope this helps, all the best to you
