CBSE

Under the moderation policy, examinees are awarded up to 15 per cent extra marks in certain papers if the questions are deemed to be difficult. In a major decision, the Central Board of Secondary Education (CBSE) has recently scrapped the moderation policy under which grace marks are given to students in exams for difficult questions. It is expected that because of this cut off marks for admission in graduation studies are likely to decrease considerably this year.

Getting a NIT is only possible when you belong to SC or ST but otherwise, it is not possible. But, you can easily get admission in private colleges and can try for government colleges. Or, you can drop for preparation of IIT and can get even IIT college.
Best of luck.

Hard work, self-study and practice should be your 3 mantras to score 95% or above in class 12th.
Good luck!

There are very few colleges offering 100% placement and they include:
IIM, Indore
Nirma University, Ahmadabad
There aren't any more credible institutes for this course. And, anyway it does not matter. If you do integrated BBA and MBA, it will take 5-years and the course fee will be very high and instead if you do 3-years BBA or BMS from a good state university affiliated colleges such as St Xavier's, KJ Somaiya, NM in Mumbai that will cost hardly 1 Lac including everything.Further, you will have more options for MBA later.

Yes, you can take direct admission in JSS.

You can do full-time Diploma in Engineering along with class 12th board in private mode. It will require extra effort and if you have the will to do both simultaneously without impacting your academic performance in both the courses, you may go ahead.

See in CBSE, since before, NCERT numerical problems are always tweaked to make it simpler or difficult, but the main aim is to make everyone score 52+ out 70 in theory so numerical problems are in average count usually. So in physics, 40% are numerical requiring least derivations 20-30% need a bit of derivation ideology too & lots in chemistry are simple NCERT modified ones that also not to a great extent. Still, check the sample papers issued by CBSE just before exams. Many problems turn common with slight modifications.

Hi,
Many UK Universities are offering direct admission in MBBS programn without any diploma/foundation. As you have provided in your information that you are taking UKCAT and Ielts, I would like to tell you that few universities in UK don't require UKCAT also for direct admission in MBBS
