A new standard for admissions test preparation — realistic mocks, focused practice, and everything you need to walk into exam day ready.
Lab45 is shaped by International Olympiad medalists, IB 45 scorers, ESAT 9.0 avg performers, and Oxbridge students. Every mock, question bank, and insight is built to make preparation sharper, more diagnostic, and easier to act on.
Every stage. One platform.
Structured courses for ESAT and Interview prep — learn the reasoning before you drill.
Start with the admissions exam you’re preparing for — ESAT, TMUA, and more as we expand.
Video lectures that show how a strong candidate thinks — taught by students who sat these exams.

A note from the founder
Preparing for Cambridge felt like a scavenger hunt. Good resources were hard to find, overpriced courses kept claiming they were the one, and I spent more time hunting and curating materials than actually studying.
My first application didn't work out. On the second try, I knew exactly what to do — which questions to drill for interviews, how to revise for ESAT, where my gaps were. That clarity made the difference.
Lab45 is the grown version of the first ESAT mock exam interface I prototyped and used myself. It's the platform I wish existed back then: quality questions from people who've actually sat these exams, a clear curriculum roadmap, and data-driven insights that tell you what to do next.
