I used the figures from the EDB website to calculate the total no. of graduates in LH, which is already different from the figure stated in LH's internal notice that you posted. Presumably the figures you have got for SC are also derived from EDB website, which may be inconsistent to SC's actual no. of K3 graduates. So it might be true that SC has 800 graduates. Can anyone confirm whether SC has 600 or 800 graduates? This may make a lot of difference in calculating the percentage of its students being able to get into the most popular schools.
I thought SC has 800 graduates (heard from a SC parent although I dunno if it is true)? LH should have around 380 graduates adding up all the 4 branches (not including the new one in Shatin). And KV around 540 graduates.
