I finished diploma in ECE , i like to jion BE , is there a good future for me of o join BE . or is there any other course to grow fast

Degree has a higher qualification status than diploma.Diploma in engg. fetches you the job of technician/technical assistant whereas B.E. updates your job profile to an engineer. Lateral entry to B.E. 2nd year possible via LEET for diploma holders.

Obviously the degree is the demand of time. Have a job and join AMIE like program. This will be good as you will get degree and experience both simultaneously.Regards/
