Ok thanks...so cool you can get into Malaysia's top 60. Is the training camp students selected from omk or another selection test? For me, omk is not easy...hard! :'( Here, can i ask an omk question (2011)?Question: Prove that any triangle can be cut into six similar triangles.(Your proof must be valid for all types of triangle but not a specific type only.) Thanks:-)

Draw all three medians from each vertex to the opposite side. This is because if the triangle split by medians then the two parts will have the same area since their base length and height is the same. (Maybe more things are needed to add in....actually I was stumped when i was in form 1...)

To learn all the basics of geometry, you should read Euclid's Elements. It is quite insightful.
