The rank you have ontained in TSECET is not that good, sorry to say, but the analysis of previous years ranks shows that the top 100 students are considered for the admission in good colleges but it does not mean that yo cannot get the college but the possibility of you getting into any govt. college is very less so you have to prepare yourself with getting into private college and you are physically handicapped so if there is any quota for physically handicaped by central committee in your state then you can apply through this quota. So, in the online counselling process check for this Physically handicapped category, you may find it there.
