For LAUTECH, I examine collections of past Post-UTME questions across faculties (Engineering, Science, Health Tech, Management, etc.).

I break down the subject-wise weight of questions (e.g. how many from Physics, Chemistry, Maths, etc.) and deduce the level of difficulty. I also note how LAUTECH sometimes recycles or twists older questions, so candidates who master the pattern gain an advantage.
