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 It is not a "prediction": the known part is locked to real numbers, and only the unpublished part carries a margin.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 · Results are history-based estimates, not official promises — no one can guarantee unpublished thresholds.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.
