I found it to be very helpful for my career development, but also allowed me time away from work with some great learning opportunities during this difficult period caused by COVID-19 pandemic which has been quite challenging! The exam was not too hard at all so if you are looking or self study material then just do it!! Don't stress about passing this test because there's no need.
It helped build confidence within myself when meeting future employers/colleagues who had already passed these tests previously and were able to offer advice etc while we where working together remotely due to Coronavirus lockdowns.
