Yes, it is worth doing.
The "General Certificate of Education 'Ordinary' Level Examination", otherwise known as the "GCE 'O' Level" or the "O Levels" is internationally-recognized qualification to determine the capabilities of middle-secondary students.
Taking the examination would also ease transferring process to other educational institutions, as sitting for this provides a recognized and standardized idea of a students educational performance.
Excelling the "GCE 'O' Level" would also sometimes help in application to colleges or universities, for that it provides a strong foundation behind the consistency of a student in the Secondary Education.
However, it is advisable to take the "International General Certificate of Secondary Education" (abbreviated as "IGSCE" or "iGCSE") or the "General Certificate of Secondary Education" (abbreviated as "GCSE") instead for a more updated qualification.
We have not been doing '0' levels for quite some years now!! If you mean can you get a GCSE in year 10 then yes you can but you need to be put forward for it by your school who determine whether it is worth you doing it a year early.
what are o levels?
'O levels were superseded in UK schools about 20 years ago. The 'O' stood for 'ordinary'. 'A' levels (advanced levels) are still in use.
There is nothing to say you cannot do 'A' Levels without doing 'O' Levels but as certain core knowledge is expected it would be hard to do 'A' without first doing 'O'. Having said that, I did Archaeology, History, and Sociology successfully at 'A' Level without ever having done any of the three at 'O' Level. The best thing is to speak to the course provider - I discussed things first with an education adviser at my local college of further education. If you check evening/Adult Education class timetables on offer locally you will find some 'A' Levels on offer but they will tend to be in subjects that most applicants will have studied to a reasonable level earlier e.g. English and Mathematics. If you are keen enough and are wiling to put in the effort I'm sure you will find a way. Good luck.
O levels are just another name for GCSEs. you have the option to either go to work after your O levels or take your A levels
