An ounce of prevention is better than a pound of cure. This is what they say.
It is always wise to prepare for any undertaking.
Prepare your things before going to school.
If you have your textbooks or any other materials for your subjects, read them way ahead. And come prepared.
If you do not have any, then use your computer and the internet to make you prepared for school.
Computer games are okay. Friendster and other social networks are also okay. But these are not the only use of computers and the internet.
There are many materials made available via the information superhighway that we will be very much behind if we fail to use them properly.
