Multitasking

First, when I manage my school tasks, I often check each deadline, and try to finish the homework which is the highest priority. I'll make enough time to finish it, for example reducing the days of part-time job, doing tasks in liblary, or starting it as early as I can. However, even if I do my best, I often have a trouble doing tasks.
To do my academic tasks more efficiently, I want my teachers to tell me about tests or academic essays as soon as possoble, and I can do enough preparation.
