Quitting current job to study full time??

I’ve passed FAR already and I’m wondering if it’s better to leave my current job and just study full time and looking for a job after.

I’ve partially been thinking of leaving for a while as I’ve been feeling burnt out for the last couple of years and my mental and physical wellbeing have definitely taken a downturn . I’ve worked at the firm for 5 years.

I’m just concerned if the job market is so bad that I could be out of work for a while. I’m also not confident how much longer they’d retain me if I don’t pass, so it kind of feels like I need to make a decision at some point.

What advice would you have??
