About TestLab
TestLab is an online MCQ practice and interview preparation platform, built by Digivo.
Our story
TestLab was founded in 2025 and is built by Digivo. It started from a simple observation: good practice questions with clear explanations were hard to find in one place, and most of them didn't help you see what you actually knew.
So TestLab brings together free multiple-choice practice across college subjects, IT, engineering and aptitude, with instant feedback on every answer, and an interview preparation section with technical questions, short and full answers, a practise mode and a day-by-day interview plan.

How we build TestLab
-
Every answer is explained
Each MCQ question comes with an explanation of the correct option, because knowing why is what makes the next question easier.
-
You answer first
The correct option and the explanation open only after you choose, so practice tests what you actually know.
-
Levels you earn
Medium unlocks when you clear Easy, and Hard when you clear Medium: 60% or more on 10 questions. Each cleared level earns a certificate.
-
Clear about what's free
MCQ practice is free and supported by ads. Interview preparation is a paid plan, and you can read a few full answers before deciding.
