Hi Ayushi!

As you have not mentioned your stream/subjects of 12th class and your result is awaited. I would suggest you to write the entrance exams related to your course ( for example: if you want MBBS you can write NEET, if you want admission in engineering college you can write Jee mains and so on). Other than this,, if you have already decided to take admission in a specific college, check on the website for admission procedure and apply for same. And yes, I would suggest you to apply to many colleges so as if you do not get your interested college then you should have a backup plan.

Hope I answered your query, thankyou!
