Hello student yes JSOS (Jharkhand State Open School) is a recognized board and its valid, eligibility criteria vary upon courses and institutes. I request you to please help me with the course you're willing to pursue further so that I can check and provide you with the exact information if you're eligible or not if you've passed high school from JSOS.

As you mentioned you're already in 5th semester of your engineering so there's nothing you need to worry about at the time of counseling admission the institution verify all the documents and then confirm candidates admission.

Feel free to comment if you've any doubt

Good luck
