Hi Disha,
Normally I would say that if you have given your 100% & worked dedicatedly towards your goals then you should be satisfied with whatever result you have got & you should keep working hard in the future but this time the scenario is very different & you guys did not get any opportunity to prove yourself. Students got very high marks in almost all the subjects everywhere & in every stream. I think there are hardly any student who hasn't scored above 80% so I think if you have scored somewhere around 90% or more, it can be considered to be good.
If you are appearing for ISC some other year then study well & you will definitely be able to score good.
Hope this helps!
