Hi ramakant, 

Neet has set the rule that the candidate who have qualified the neet entrance exam and then get a seat through counselling process have minimum50% aggregate marks in pcb for general category and 40% for obc, st and sc. 

You can give improvement exams this year and then can try for neet next year. 

If you will have any doubt you can ask us. 

Dear aspirant,
 Since by scoring above 40% in boards you have met the basic eligibilty criteria for neet, but to get a seat at government medical college you need to score good marks comparatively with other students applying in maharastra state quota and fall under the cut off rank in merit list.According to previous years cut off analysis which is subjective as cut off ranks change every year,depending upon level of difficulty of neet this year,no of candidates applying to neet this year to govt colleges through maharastra state quota (from obc category ) also rank fallout pattern is entirely different from previous year so nothing can be predicted with 100% sureity, keeping in mind above factors cut off through state quota for maharatra(obc) category goes around  33318 (rank) against 472 marks,since rank fallout pattern against marks is entirely different this year , so you might or might not get a chance.

Also if you want more analysis regarding colleges you cant get using above score you can use following toolhttps://medicine.careers360.com/neet-college-predictor

Hope this helps
