I can understand your feeling. But please understand that your job is done. You’ve written your exams well and now you don’t have to worry.
I know that it’s about 90% preparation and 10% luck factor. But please leave the luck factor to God (or destiny). You know what, in my 10th result (2018) all toppers including me got very poor marks in English and Social Science. My former school got poor result in Hindi. Some applied for reval, some didn’t. It’s just like that.
Coming back to your question, mostly it will be lenient and you’ll get marks for what you’ve written plus some bonus if you’ve written/attempted questions which you didn’t know but tried. Understand? Even I was not able to concentrate on other things because of this tension. But soon I realized MY JOB IS DONE.
