This question already has an answer here:
I studied at the top university of my country (well-known in the world), obtained top grades, grants, bursaries, had some of my research published, was hopeful of an academic future... but then I had health problems and deferred indefinitely just short of 2 modules. I took a few years off and since I had to finance myself, I started a career in a field not entirely related to my studies (but still a good one, a bit like studying any Science helps one get a career in banking) and have been very successful there as well, was promoted twice already - but my health is irregular again, severely affecting my performance. I fear I might end up unemployed soon, but only because my current job has an extremely high-pressure environment. Therefore, I think I would thrive much better in a a more senior position in a company which does not have such a dog-eat-dog work culture.
In any case, my question is: how (and how much) should I explain on my CV?
Should I leave out my education and focus entirely on my career progression, or should I include my studies, including all the top achievements, valedictorian grants, etc. and just on the side mention that it is incomplete?
EDIT: (to answer a question in one of the answers below) my health problems are directly influenced by high pressure work, stress and irregular hours. The more balanced and flexible the workplace, the more chances I have of curing myself.
