Instead of obtaining admission for all the papers in any single institute, it might be better to search for the experienced and well known teacher for the respective subject, and than take admission in the institute where that teacher is available.
By saying that, I do not mean that only experienced and well known teachers can teach properly. Some times, it happens that a new teacher teaches in very attractive manner.
Another approach is to ask the administration of any institute for the demo classes before properly taking admission. If the style of the teacher satisfies you, continue with him/her, otherwise try some where else.
