Conjugate Priors in ASM

I am just about to start credibility in ASM and I was curious if lessons 47-50(conjugate priors) can be calculated using first principles obtained in lessons 45 and 46. I know the lessons can save time on an exam, but I very much prefer to calculate problems from first principles, and if possible, I'd prefer to go that route. Just hoping for some insight, any is appreciated!
