Hello Chanpisey,
Welcome to the 5steps website!
A big IELTS is coming up soon. However, I am not ready to take the test, cos my reading is too low, in addition to this, I always run out of time, and therefore, I have to guess. Since I practiced reading, I realize that the majority of my guessing is not accurate at all.
What should I do to control the time given? I am completely stuck! What should I do if the result is not satisfactory enough. I wish to get at least 6.0. Otherwise, my mom might be too disappointed on me. I have been trying my best, but it seems nothing can be improved.
I bet, the IELTS test is arriving on 19th, isn't it? Well, it's a bit too soon but I hope you have been prepared for it.

Anyway, my suggestion for time management in reading is that you don't have to spend too much time for each question. In fact, i'm not an expert or something in IELTS but I am just one of the students who wish to take the TOEFL and want to share ideas

.
Spending more time on each question in reading section won't help you get the anwers correct. Well, as we think, you first should read the whole passage and notice the remarkable places/people....in the passge...When you come to the questions, you have an easier time finding the answers.
Guessing all the time is not a good way, so you need to have enough ability for it too. Any good score of either the TOEFL or IELTS depends on our test skills and real ability of our own. Believe in yourself, Pisey. I believe you have prepared for it and a few days before the test you should relax. Don't cram for the exam. It leaves you restless and anxious.
Hope other members will share more ideas for you!
Good luck!
Somala
