Hi aspirant

If you are intrested in engineering then at first you should make your concepts clear .It means you have very less score in PCM and whatever you have studied in indermediate the same you will have to study in your engineering.

If you are not good at PCM then definately you will start failing in B.Tech/B.E from the first semester.

So i suggest you to take a drop and then appear in entrances like JEE,BITSAT,SRMJEE,VITEEE,Manipal,GITAM etc.

On the basis of score of these exams you can get college.

Hope this was helpful.
