Our Physics class was split up in to 3 different options this year.
In the end, we did not do an assessment task for an option module other than our trial.
I do not recommend it unless you have someone else doing the same option as you.
Also, you have to have a passion for the option. I did Age of Silicon because I wanted to get a taste of electrical engineering, which consequently persuaded me to do it as a future uni degree.
Chemistry of Art will only tie in with learning about quantum mechanics. So you should NOT do this module if you don't do q2q for Physics.
Also, Industrial Chemistry will be much more beneficial later on in life or for uni.
But, if your teacher said it is fine to do your own option, then make sure there is no assessment task for the option modules.
