In California, any retailers that sell rechargeable batteries are required to accept used rechargeable batteries for reuse, recycling or disposal. Car batteries can be recycled at auto shops, and this is normally taken care of for you when you have your battery changed.
A perfect ACT score is 36. This refers to the Composite Score, since it is an average of the four main sections. In other words, a perfect ACT score is a 36 in English, a 36 in Math, a 36 Reading, a 36 in Science, and therefore a 36 Composite score. If the Writing Test is taken, a combined English/Writing perfect score would also be 36 (remember that the Writing Test Score is not calculated for the Composite Score).
I recommend that you use the 75th percentile average as your target score. If you achieve this score through hard work, you'll have a very strong shot at getting into many of the schools on your list. For you, this is what a good ACT score is. This is your personal goal-not your friends' goals, and not your parents' goals. Finally, you should set a target for your score for each section. My suggestion would be to use the composite score for each section.
