HKUST QR Code vs GradeReach

The HKUST QR Code is a tool designed for HKUST members (such as students and staff) to generate their own secure, dynamic and personalized QR codes that can be used for access purposes, such as opening doors with a Smartdoor Panel.

GradeReach helps CAIE A-Level students turn AS results into a concrete A2 target: exactly what raw marks you need on the remaining papers to reach the grade you want. HOW IT WORKS Total boundary = AS boundary + A2 part. The AS boundary uses the official, already-published thresholds for your exact session — zero estimation. The A2 part takes the highest of the recent sessions (excluding the India-region March series), so it leans conservative. It is not a "prediction": the known part is locked to real numbers, and only the unpublished part carries a margin. FEATURES · Reverse target: pick a subject, enter your AS raw marks, choose a target grade (A*/A/B/C), and get the weighted A2 score you need. · Safe line: beyond "just enough," a second line calibrated on each subject's own history — in backtests it undershoots roughly 1 in 10. · Update as you go: already sat an A2 paper? Enter your estimated mark and the result becomes "what's left to score on the remaining papers." · Practice log: every past paper is judged against its own session's real boundary — pass or not, and by how many marks; a trend chart shows how steady you are. · Combination check: if an AS paper combination can't carry forward to a full A Level, the app stops you and explains why. WHO IT'S FOR · A-Level students who want a concrete score target · Anyone asking "how good was that practice attempt, really?" NOTES · Not affiliated with or endorsed by CAIE / Cambridge. Data comes from publicly published historical grade thresholds. · Results are history-based estimates, not official promises — no one can guarantee unpublished thresholds. · Your data stays on your device and, with iCloud, syncs only across your own devices. We never see it. The full version is a one-time purchase that unlocks all subjects and features.
