I did my 12th in 2019 and got 72%. Can I sit in Jee Main exam?

Dear student, MHRD made a few changes regarding the eligibility criteria for appearing in JEE Mains exam back in 2017. The official statement released said that the students with less than 75% in boards are not barred from appearing in JEE Mains exam, but won't be able to get a seat in IITs, NITs, IIITs or GFTIs. You can go for other colleges of they accept you.

• The percentile calculation will be done for the required subjects in a single academic year only. Therefore, candidates appearing for improvement in Board examinations can EITHER appear in one or more subjects and secure 75% aggregate marks (65% for SC, ST and PwD) after improvement, OR, appear for improvement in ALL subjects to be in top 20 percentile (see section titled “Regarding the cut-off marks for the top 20 percentile”) of the corresponding academic year.
• The marks scored in the following five subjects will be considered for calculating the aggregate marks and the cut-off marks for fulfilling the top 20 percentile criterion.PhysicsChemistryMathematicsA language (if the candidate has taken more than one language, then the language with the higher marks will be considered)Any subject other than the above four (the subject with the highest marks will be considered).
• For calculation of the total marks for five subjects, if the marks awarded in a subject is NOT out of 100, then the marks will be scaled (up or down) to 100 so that the total aggregate marks is out of 500.
• If a Board awards only letter grades without providing an equivalent percentage of marks on the grade sheet, the candidate should obtain a certificate from the Board specifying the equivalent marks and submit it at the time of acceptance of the allocated seat. In case such a certificate is not provided, the decision taken by the Joint Implementation Committee of JEE (Advanced) 2018 will be final.
• In case any of the subjects Physics, Chemistry, Mathematics and Language are not evaluated in the final year (e.g., in a 3-year diploma course), then the marks for the same subject from the previous year/s will be used for calculating percentage of aggregate marks.
• For candidates who appeared in the Class XII (or equivalent) Board examination for the first time in 2017 and reappeared in ALL subjects (for whatsoever reason) in 2018, the best of the two performances will be considered.
• If a Board gives aggregate marks considering both Class XI and Class XII examinations (in the 10+2 system), then only Class XII marks will be considered. If a Board gives aggregate marks considering the results of all three years of a 3-year diploma or courses of equivalent duration, then only the marks scored in the final year will be considered. Similarly, for Boards which follow a semester system, the marks scored in the final two semesters will be considered.
• If a Board does not give marks scored in individual subjects but gives only the aggregate marks, then the aggregate marks given by the Board will be considered as such.
