I have 38 marks in maths , 52 in physics , 48 in chemistry in hsc , and 180 in electrical maintenance, I'm I eligible for btech in Maharash

You are not eligible for B.Tech in Maharashtra as you are not at par with the basic eligibility criteria of all engineering colleges.

You can opt for other courses like Bsc in specialisation fields like physics, chemistry, aviation industry.
For aviation, you can look out for both private and government colleges in Mumbai, Pune and Nashik. Few of the colleges are Bombay Flying Club(Mumbai), Indian Aerospace and Engineering(Mumbai), Phoenix Aviation Academy - Mumbai, HAL Pravara Aviation Institute - Nashik.
Other fields you can look for courses is marines, biotechnology, travel and tourism, hotel management, environmental science, journalism or media courses.
All the above mentioned courses have a wide scope as career fields and will lead you to a great future.
