<p>Can anyone recommend any books or websites that I could use to get a headstart on learning the sciences? I'm going to be in grade 11 this year and am planning on taking the Canadian Chemistry Contest as well as the others. I'm looking to do well on these and hopefully get some sort of award. </p>
<p>Also, if anyone has taken these contests before, how are they? Is the content covered in the curriculum?</p>
<p>Thanks in advance.</p>
