I'm a +2 candidate.Can I straight away do PG like courses CS& IT or if any other what will be ur suggestion in prefering updated course?!
No you don't directly do PG Courses without entering into College/University by giving some exams like JEE MAINS,JEE ADVANCE, WBJEE etc.
No Sasiregha you cannot directly do postgraduation courses. As you are interested in CS & IT field so first do B.Tech (4-years programme) engineering in any of these courses then you can do masters (2-years) i.e. Post graduation in any of the specific specialization related to these fields. In some of the colleges, you will also get a chance to do integrated programme i.e. B.Tech+M.Tech (5 years) so you can also directly go for these programmes. But as I told earlier there is no direct route of doing post graduation in any of these fields.
Feel free to ask if you have any more queries. All the best!!
