The school should introduce some subjects which helps us in practical world (like speaking, knowledge of law, knowledge of finance and how to invest it) as this will only need some new members with these type of knowledge and i think this is the resource which they are using it. Other than that digital world is taking pace so why not teaching them with animation, whether its is kid or an adult everyone like animation and the bright colours and it will help in better understanding for them because it is scientifically proved that we are easily able of remember the vision or the things which we saw compared to things we read or learn through imagination.

Firstly, you should buy the IELTS Book ( the general one which has every module Reading Writing Listening and speaking) Then you can should understand the pattern of each and every module how and what type of questions are generally asked. ( This can be done by taking help from youtube) Lastly, you can try to attend the classes for it or you can take help from the one who has already given it. Now how to manage the time, you can beleive me as i also given it and for preparing it only takes regular 2 to 2 n half hour regularly.
