hi,

see 20 is a not a very old age to again try for sbi exams , if you have seen it most of the candidates who sit for bank po like exams are between ages of 22-25, so the people bigger of your age are trying to crack it, even if you follow careers360 different types of career related query you may have seen that peoples are from age of above 40 , wants to pursue bachelors course or want to again pass the school leaving certificate.  so now its upon you, another thing you need to questions yourself whether you are really interested for bank or any other official jobs or you want to do some thing apart from this. see there is many of careers line, we should only focus on the path where we find the interest to learn. so think wisely, dont just make a decision based on what others people or relative would say.

hope you may understand.
