A lot of excitement there
Back on topic,
So, I believe there are innumerable courses you can take up during the time of holidays as (of course what else can be done after S.S.C? The Intermediate

) earlier or later, the college will start in the first week of june. (Well, depends on what college you choose)
There are two classified standards Intermediate and Vocational Intermediate Which are Nationally recognized. So, in that again, the subjects vary. Intermediate will have like the general M.P.C, Bi.P.C, M.E.C etc And Vocational has a lot of streams to choose.
I won't recommend the Vocational unless you're planning for higher studies in the courses vocational board(s) provide. Not meaning it's bad, but anyone who does/takes it needs the specific interest in the subjects otherwise, it's a chew.
If you're further looking into them, you'll have like Computer Graphics and animation, Computer sciences and engineering, Medical Lab Technicians etc
In general, once you do the course, you can get a job. That's one of the purposes of Vocational courses.
I don't know if you guys have it, but there's an implementation done to the Normal intermediate which was done for the Vocational one earlier i.e Bridge Course.
If you take up Bridge course when you join a college, you'll have the ability to choose the subjects that you might want to pursue parallel to your main stream subjects. Like you're eligible for medical colleges even when you do M.P.C etc. That'd sure be a burden but you'll have various options once you complete your
Intermediate.
The range of freedom of the subjects that you want to study is getting much better every year and hopefully, you'll have more good courses/colleges to study.
