CBSE 12th

You have to apply for BSc with Botany Hons

Yeah, from next year board marks won't be considered.

It depends upon your caliber and your level of comfort with self learning. If you are the kind of person who just needs a little guidance and can do wonders with it, then take the distance learning program. If you think you need constant attention, push, and someone to explain things to you, then take regular coaching. However, coaching has lesser role to play in your success than your own. Ultimately what will matter will be your practice, your understanding, confidence and stress management.

Since you are keen in acting,you could pursue a degree in Performing Arts .The Bollywood industry is full of successful people who have no connections in the Industry .If you are good and have a passion in acting then you could pursue it as a career as well. Offlate the TV industry also has to offer a lucrative career in multiple areas of performing arts.
Alternately you could pursue BBA/Mass communication and peruse a diploma/certificate course in acting and thus minimize the career risk by keeping career option outside the entertainment industry also open
