This is actually a difficult decision, as it varies among every individual. Go for a drop only if you are confident enough and well prepared for the exams next year. If not, it is better to join the college and make it count. 

B.Tech is overall a very good course with lots of scope for scoring good marks and learning new things. Though Bundelkhand University may not be one of the popular choices for students to opt for B.Tech, if you want to study here, it is fine. 

It is suggested that if you are an average student do not drop a year but go for Bundelkhand University. Remember that while studying there try not to meddle with the local people as it could sometimes take a wrong turn.
