We do plan to add more subjects over time, but each subject and syllabus takes significant time to digitalise properly because we build the content carefully by hand with experienced educators, rather than relying on AI-generated material.

What's the definition of Waves?

But Why...

Studying can feel overwhelming, expensive and involves juggling many different resources just to stay on track. Many students spend a lot on extra help, yet still leave feeling like the support is inconsistent and the learning experience falls short of what they truly need. At the same time, quick-answer culture can make studying feel more about getting answers fast than actually understanding.
