I practice usually in the morning time before heading to work. Listening only, previously i never did practice for reading but after the horror of last test, i will allot time for reading this time. For writing i usually practice in the evenings and night. As for speaking i watch few sample videos on youtube before heading to test day. I know how hard it is do anything with kids around. I have seen my elder sister raise two kids all by herself on top of taking care of a big baby in me lol. I don't know how ladies do it. I don't think i would be able to take that much, seriously.
