Strengths/Weaknesses In Chemistry

I'll start with my STRENGTHS :)

The most probable MAJOR reason i decided to take Chemistry as a course was because I was most interested in it. At the time (I decided to take Chemistry at Grade 7) Chemistry was really easy - mostly because it was only the really easy stuff, such as the basics of the Reactivity Series and Earth Chemistry. I also used to think that it would be fun making explosions in the lab :P. My strength used to be Transition metals, but i think that Organic Chemistry - excluding polymers - is where I am strongest now.

And now my WEAKNESSES :(

I'll start with what contradicts with my first strength, i.e. - Chemistry gets tougher as the basic years go by. I was naíve back then, and I thought it would all be easy. I am probably weakest at the Mole Concept.
