Hi

All you need is determination -

• Make subject wise plan and strictly follow that plan
• Focus on improving your problem-solving speed, which requires continuous practice. Drill yourself with regular numerical problem practice
• Start giving mock tests and solve previous year question papers and sample papers
• Solve at least 40-80 numerical problems daily which includes physics, chemistry and, mathematics. Set time limits for questions.

Remember, just 6 hours of mindful study , daily will give you a wonderful result

Hope this helps!
