With limited resources available for a specific A-Level qualification, I decided to take it upon myself to make a website that provided free revision and course materials for the course. I considered this to be a good idea because the market was definitely there and I could have generated some money from the site.

I began advertising some aspects of the site last night to students who were sitting an exam on the subject soon. Today I decided to Google the subject (low competition so just by searching the subject name, my website would've appeared). Instead of finding my website ranked on Google, I found a news report published this morning which reported the scrapping of several qualifications by the exams regulator. The subject that my website was based on, one of many scrapped.

I think that is bad luck.
