Perfect or authentic playthrough?

When you’re playing books like BOLAS or ILITW, where how well you do depends on whether you choose the correct options, do you opt for:

A) A perfect playthrough, where you look up the walkthrough so that you can get all the correct answers and gain the maximum points possible (if the book has points),

B) An authentic playthrough, where you play it without walkthroughs, simply accepting when you choose the wrong oprions, or

C) A mix between the two, where you alternate between using a walkthrough and doing it blind.
