CA syllabus is huge but you need to see it as a long term goal. Break it down into smaller parts and focus on one subject at a time. Make notes, practice as many questions as you can and clarify your doubts regularly. You’ll succeed if you put in consistent effort and don’t lose hope. All the best!

Start practicing past year papers and question banks as early as possible. This will help you identify your weaknesses and work on them before the exams.
