CBSE 12th

I am not discouraging you but I would suggest you to go for B.Sc and proceed ahead. If you accept my suggestion, then either go for B.Sc in Physics or B.Sc in Maths.
Feel free to ask more.
Good luck.

If you are looking at pursuing a degree course, then 60% is a bit low for it. But you can go for an undergraduate diploma course, as you can get admission for those course with your academic profile. Please check Langara college's website if they offer diploma courses in a specialization of your choice or not.

At this score, your chances seems low. You must score at least 90+ percentile in CAT if you belong to general category to get one of the top 30 B-Schools.

After class 12th, you can't earn lots of money. So, you should go for Bachelor degree.

Dear Imran,
First, change your mindset towards your career.You should focus on how to obtain knowledge and professional degree rather than thinking about placement or money.
If you have knowledge, good IQ level and good foundation related to your field than you can earn well and live your life in a better way.
Choose the field related to your caliber and area of interest.
All the best.

In improvement exam only those subject marks get changed, which you are going to write again, other remain the same.

You can opt for software and hardware courses, and if you want to get a job, then opt for DTP course.
