The school, actually it is supposed to be called institute but somehow they named the institute as school, is a complete crap. I have just realized the saying "Do not blame people for disappointing you, blame yourself for expecting too much from them". This was the cheapest option to me for the visa extension.
The school system and curriculum do not seem to be working there. Even teachers are not well educated, perhaps less educated than their students. No document standard exists in the school. Just for one assessment, there are numerous separate papers including assessment, printed slide, appendix etc,. Making a booklet by stapling all the papers together can be the simplest and best solution to the problem. It is hard to believe but truth is no one give a shout about it.
Again, do not blame people for disappointing you, blame yourself for expecting too much from them.
