Hello. You have not shown the challenges to which this question refers, which may leave the answer inaccurate. However, I will try to help you in the best possible way.
In general, we can say that the study habits for each challenge are similar because they all require concentration and dedication so that they can be carried out. It is not possible to establish a study habit without concentration and dedication whatever the challenge.
Regarding the differences, it is necessary to assess the degree of difficulty of each challenge, since the differences will be associated with the ability to adapt habits to the challenges and the ability to solve them.
