This 2021 post reviews four students who contacted me after choosing universities in Singapore, including the National University of Singapore. There may have been other students who did not get in touch, so this is a collection of individual examples rather than a complete admissions dataset.
All four students discussed in the original post had earned a final grade 7 in IB Chemistry. Their reported predicted totals were above 40, including scores of 43 and 44.

The first student was reported to have an IB predicted total of 43, along with an English-language result that was not specified in the post. The student had struggled at the beginning, then became much more consistent and finished the IB strongly.

The second student had a reported predicted total of 44 and no additional test score listed in the article. The student was diligent throughout the course and later confirmed an NUS admission.

For another student, the parent sent the admission news first. The post also reported a predicted total of 44 for this student and expressed gratitude for the result.

The students were applying through the three-year overseas Korean admissions pathway. The article's closing summary says that their predicted totals were all above 40 and that none of the four had a perfect 45.
At the time, the author estimated that a total around 43 could be competitive for some Singapore university programmes, depending on the course. This is a historical personal observation from 2021, not a current admissions requirement; applicants should always check the latest official criteria for their chosen programme.
The original article ended by directing readers to additional Chemistry education information at aplecture.com. That site and its promotional image are no longer available, so the archive card below preserves the reference without leaving a broken image.
