Greetings Pratik!

Hope you're doing great.

I can feel what you must be going through. Getting supplementary in 12th exams not only hampers college admission process but, it also creates psychological stress of losing one complete year. Since it's impossible to undo what had happened, right now you should focus on preparing for next year competitive examination.

I'm sorry but in order to appear for MHT-CET counselling, you need to clear your 12th compartment papers. The compartment examinations are generally arranged in the month of August and it won't be possible to get the result before MHT-CET counselling date. MHT-ECT counselling date will fall in the month of June 2019.

You can also opt paper rechecking option if you're near passing marks. If luck falls into your favour, who might know you'll get that extra grace marks that will certainly provide passing marks in that subject. More or less, it's time to rethink about your career plans and don't forget it's never too late to start off fresh.

This should be your strategy night now:

• Prepare for your compartment
• Focus on next year competitive exams to make the best use of one year time(in case if this happens)
• Never look down in front of friends, after all, it's life and everyone fails.
• You should clear your mind the kind of career you're really looking forward to.
  

Hope this will help. :)
