Hi dear,

Hope you are doing well!

Now let's go through your question.

Basically, the subjects are quite interesting such as fashion designing, english, economics, political science, geography, history, psychology, philosophy, entrepreneurship etc. 

Apart from this, there are some optional subjects too. The subjects included in the arts stream are mostly theory based.

Note this things:

• Prepare according to the prescribed syllabus

• Make notes of all the relevant topics.
• Go for the previous year question papers and get an idea of the weightage of each section as well as a pattern of the question paper.
• Take revision of all the topis prepared before appearing for the exams.

• Managing time is the most important part while preparing for board exams. Prepare according to the schedule.

Thank You & All the best!
