Distance learning B.Tech courses are not recognized by MHRD, DEC and AICTE. Hence never do such type of courses if offered by some institutes. In my opinion, you should go with lateral entry B.Tech regular courses offered by some reputed institutions like Thapar Institute of Engineering and Technology, Delhi Technological University, Punjab University, etc.

Restarting your study is a great decision. The BBA course about which you asked is a distance learning program of three years in Wisdom School of Management. The eligibility criteria of this course is class 12th in any stream with 45% aggregate marks.
Further, Wisdom is a non-university institution. All programs of Wisdom are autonomous and do not come under the preview of UGC / AICTE.

Dear Ajay,
Your rank should be under 400 for IET, Lucknow.

Much depends on the University. It has its own regulations. Generally, there is no problem for promotion. The backlog can be cleared later, in a Supplementary Examination.

Yes, online housekeeping is available, but the fee structure depends on the institute from which your taking and for how many years. You can get in contact with them and you can access to their portal.
