Hello Aspirant,

By analysing your query , you want to give your ts intermediate board in private right ?

If I am correct then you can give your 12th examination. But kindly note that in that examination you should opt Physics Chemistry and Mathematics as their compulsory subjects otherwise it won't be valid as the eligibility criteria of jee mains demands this.

Candidate should secure a minimum of 75 percentage in their class 12th in order to sit for the jee mains and advanced examination.

I would recommend you to kindly focus on your 12th preparation along with jee with jee's preparation having more weightage.
