Hello Aspirant,

First of all don't assume yourself as a loser/weak because nobody born loser, it is all your works which makes you a loser so if you want to do something in life then you have to do the works which are appropriate and of your interest. As you have mentioned that you want to prepare for Banking sector and in most of the sections you were strong earlier so this is the good thing, now you have to just look out the things and practice some questions for those sections you will regain your consciousness for that subject, for e.g., you were good in Quant. and Reasoning so just practice some questions and devote some time to this section you will regain all the power of this subject. If you are preparing for Banking sector then you can go for SBI PO or SBI Clerk or IBPS provided that you complete your graduation by next year because for almost all banking exams only graduate candidates are eligible or those who are in final year of their graduation.

Age limit for SBI Clerk is 20-28 years, for SBI PO it is 21-30 years and for IBPS Clerk it is 20-28 years. So you have enough time to prepare for banking examinations but if you start your preparation in a right way from right now then you may crack these banking exams in just one year.
