Not at all. Always remember, it’s never too late to learn anything 🙂 Since you’re in grade 12th, you can probably start with focusing on your grade 12th syllabus & try to finish it within the next few months. In the remaining time, revising your grade 9th to 11th syllabus would help you remember the concepts. The keys to cracking any competitive exams are:
- Understanding the objective and pattern of the exam.
- Having a schedule & plan for your studies.
- Clearing the basics of your subjects.
- Figuring out your strengths & weaknesses.
- Strengthening your strengths.
- Improving on your weaknesses with practise.
