Mechanical Engineering

Yes, you can apply into the colleges you want to pursue engineering from and if you score good marks in Diploma course, then you can pursue it. Good luck.

First congrats on taking mechanical engineering as the optional subject. Get hold of the syllabus. Analyse previous papers to know which topics are more important. Set weekly targets to complete the topics. Use weekends well. Revise once a topic is complete. Once all this is complete give test series.

Can I know your aggregate marks of PCM/PCB?
