FAQ
Common questions
From students
“I went from not knowing what 'evaluation' even meant to getting 5/6 on my second draft. The 'Fix this first' section is the only feedback I needed.”
IB Chemistry student — Year 2
“Submitted my first Biology IA draft and iBacalao told me my research question was missing the independent variable. My teacher said the same thing two weeks later.”
IB Biology student — Year 1
“I thought my conclusion was fine. The criterion breakdown showed I hadn't linked it to my data once. Changed that and moved from a 4 to a 6.”
IB Physics student — Year 2
