Hi,
Usually the improvement exam pattern has its syllabus same as the one you have studied. So I don't think there will be much changes in the exam patterns.
All the best and do well if you are answering.

Hello dear student, 
Greetings
If you are not satisfied with your marks and you think that if you get another chance  you can score a high percentage and you are ready to work hard for it then it's a good decision to give improvement exam. Regarding change in syllabus and patterns,  I will say that there's only a slight and nominal change in the syllabus and pattern. So just make up your mind and get ready to work hard and score a good marks,  also you don't need to give your practical exams again.
Good luck
Thankyou

Hello Aspirant,

If you are a candidate of betterment, you will give examination based on the old syllabus. There will be two question paper of at all there is a change in syllabus one for the regular candidates and one for the repeat candidates. Under no circumstances will you be allowed to give your repeat examination based on new syllabus.

Good Luck
