BBA

Honestly you will have to study a lot, around 10-12 hours a day if you actually want to have a decent shot at clearing the exam.
1) Divide your time between the 4 sections equally.
2) Do a lot of reading from TOI/HT and ET for GA. Also review basic Science and social Science (ex which president signed emergency? )
3) For English do comprehensions and grammatical problems
4)LR and QA do a lot of practise questions in different subsections. Remember to understand where your strength lies and work on them rather than working on your weaknesses because that ain't gonna help in 15 days.
