polytechnic or polytechnic Le me different

I don't understand what you want to ask?

Polytechnics usually provide the Diploma courses in Engineering. The admission are done on the basis of the entrances organized by different states. After the successful completion of the Diploma, if one wants to do BTech then he/she can take admission through lateral entry directly to the 2nd year of BTech.

I would recommend you to repost the question with proper question specifics so that we can provide all the information required.
