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).
The ACT makers actually design the test so the target average score is about a 20, and the target section score is 20 on each ACT section as well. Remember that the lowest score you can get on the ACT total is 1, and the highest you can get is 36.
