I m doing btech and have 17 papers to clear in the final sem.i ve lost confidence.plz help?

You dont have to do all 17 papers at one stretch right? Just split the papers into two batches and start preparing for them. No point in losing confidence. Just start doing. YOu have no other choice. Split your syllabus into small schedules and keep completing them. YOu will soon find that you have completed almost everything. Dont think about the past but also dont llose the future . All the best of luck to you. You can do it.
