Is it worth doing the Knowledge of london? While working part time

I’ve always wanted to do the knowledge of London. I’m a kitchen porter, it’s an ok job and but also looking to request to go part time hours possibly at the weekends. Giving me five free days to study and do what I like. My old man was a black London taxi driver for over 30 years and want to make him proud by doing this. Im guessing need money for Petrol to put inside the bike and while doing the runs of knowledge. I’m really up for this and maybe join a Knowledge school in the process. Please help, big thanks in advance.
