CBSE 10th

There are many good institutes in Mumbai, It is really tough to directly comment on which one is best among, especially in INDIA for domains like VFX/Graphic designing/ web designing, animation and VFX/editing/post production or gaming etc. where many institutes offer many types of courses for different duration for almost all the same pipeline .
We need to see the content of the course , duration, cost , infra, earlier students outputs and skill developed , in-time course completion record , certification process & delivery of certificate in time etc.
Also Same Brand has different centers and branches and unfortunately all does not perform the same . Some centers are doing great some not, in vary place to place centers to centers and also on the local management & team.
So its always good to visit the institute personally, speak to them, see the track record and then decide if its up to the mark as per your requirement.

Ragini, your son can go for a diploma course in CSE, ECE, EE, ME, CE, Automobile etc. And a better option for him would be to join integrated Diploma B.Tech course where he save his one year as well as pressure of entrance tests.
After doing a diploma he will get direct admission in second year of B.Tech. There are many universities in India that are offering these integrated Diploma- B.Tech courses. Some of them are also offering scholarships based on percentage in previous qualification.
So, i feel instead of simply doing a diploma and then again starting with the search for a college/ university for B.Tech or doing 12th and then giving entrance exams and wait for admission in some good institute.it is better to take admission in an integrated Diploma-B.Tech course.
