I have a bright 16-year-old struggling with chemistry too (although her general problem is organization and having a good memory so she has gotten away with not developing great study skills).
Even through my husband and I could help her in chemistry, we went ahead and hired a tutor. We've found it much easier and less stressful to have someone else work with her, and the tutoring does seem to be helping quite a bit.
There is no arriving, ever. It is all a continual becoming.
