Is that write or wrong to take long term coaching,..please give me a good suggestion
Taking coaching classes and for how much duration totally depends on you.
Every student has different ability to understand the new topics.
If you are taking coaching classes it is very important that you do self study as well. Make sure you build strong base. Clear all the doubts in your classes.
If you want you can make your time table according to your comfort to keep a track on your performance. So, that you can complete your syllabus on time and you get enough time for revision.
Solve previous year papers to understand the pattern of the exam and level of the questions you can also solve complete mock test series for your practice.
All the best!!
