GCSE Additional Science (Additional Science) is equivalent to Double Science (Integrated Science). It combines the three subjects of biology, chemistry and physics, equivalent to two GCSE subjects, and finally obtains two certificates. Triple science studies three subjects separately, and the content of study is more in-depth.

In university applications, Triple Science has an advantage over Additional Science. Although GCSE Additional Science is easier than Triple Science, if you want to apply for a STEM field, then Triple Science will improve your chances of gaining admission.
