Thanks for your reply brother.

If you suggest joining academy for mock exams, and subjects specialists for preparation, i could do that. It'll help alot i guess if i knew about structure, how to attempt questions, and all those stuff from other aspirants or senior teachers and then practice myself.
As for Disability, I've been studying in normal schools from young age, not special, so i'm used to it. As for CSS, i do plan to prepare with my University colleagues, when attending a lecture, they do make notes which i help copy and learn from Internet and books on my own, so it'll work out in Academies too i guess.
So thank you, i guess i'll have to join Academy for a while to learn everything then decide if i should continue or carry on my own.
