i probably should've recorded this in my description. i already looked at the resources in the other bos site but they dont have too many there.
Yeah, there's not many past papers that you have find for Preliminary course.
Well, my teacher told me that the BEST practice is doing those questions from the textbooks like Conquering, but if you have other textbooks it's fine, as long as you have something to practice with. Some study guides also have some practice questions in there, so, you may as well try that too.
(but of course, Past Papers are the BEST!!)
Or many be just go to your chem teacher and ask he/she for the past papers from your school. I'm sure he/she would be really happy if you ask!! :uhhuh:
Hope this can help you a bit.
