Hello,
Yes, you can clear the exam in one and a half month if you study with the right strategy. Many students have prepared in a short time and still scored well by focusing only on the most important chapters and practicing questions daily. You need to revise high weightage topics from all three subjects and solve previous year papers regularly. Give mock tests every two or three days to understand your weak areas. Keep your schedule simple and consistent. If you avoid distractions and focus only on scoring chapters, it is possible to clear the exam in this time.
Hope this helps you.
