What this is, what it isn't

What it is: the four things that exist nowhere else for SL AL Chemistry —

• An AI tutor that has read the official Resource Books and every past paper since 2003.
• An interactive periodic table tuned to what AL examiners test (Cr/Cu anomalies, flame colours, oxidation states).
• Chemistry calculators matched to Paper II calculation style.
• Past papers searchable by topic, not just by year.

What it isn't: a replacement for textbooks, classes, or your teachers. It's a complement.
