How it’s worked out
Aggregate = test percentile × 60% + FSc Part-1 % × 25% + Matric % × 15%.
Worked example: Matric 950 of 1100 (86.36%), FSc Part-1 450 of 550 (81.82%), test percentile 80: 80 × 60% + 81.82 × 25% + 86.36 × 15% = 81.41%.
- From PIEAS's admissions FAQ: aggregate = 0.60 × test percentile score + 0.25 × HSSC (Part 1) % + 0.15 × SSC %. The BS information leaflet gives the same split.
- The test counts as a percentile (how you did compared with everyone who took it), not as raw marks.
- You need at least 60% in both Matric (or O-level) and intermediate (or A-level). SAT II and ACT applicants are ranked on a separate list.
