It is good to see I am not the only one who hasnt jumped straight back into school work for term 2. I am having a similar problem aswell, procrastination is becoming a daily ritual. The only subject I am really taking seriously is Maths.
Shock has a habit of shaking me out of my apathy. I have started to take my maths much more seriously after failing my extension test. I know its a negative thought but maybe a bad result or something of that nature will bring you back on track. Dont forget that a bad experience can always bring something positive.
Also remind yourself of what you want, what is your goal. It may be recieving a UAI of 100 or topping all your subjects, it is only through hard work and determination that you will get there. Stay focused, you might have burnt out after term one but I'm sure you will pick yourself up and get back on track. Keep us posted on what happens.
