Hello Ayesha,

First of all,let me tell you that everything can be achieved by on own practice and hardwork. But, it also requires proper guidance and coaching under professionals.

So,if you are planning to crack the examination with self study then you may go for it,but it would be more effective and beneficial if you get in touch with a coach.

The experienced individuals would introduce more new terms and provide you with the latest,which you might not be able to achieve by your own. You also get a better understanding about the COMPETITION, more properly going around in the particular field or stream.

I hope you understood my point.

All the best.
