HSEB Query

I had shifted to abroad after giving exams on 2071 and 2072 when the board was known as hseb but I did not pass in 2 subjects in both years. So I decided to return this year to complete my studies here. It is 2075 now and and hseb is changed to neb. It has been 4 years since I gave grade 11th regular exam and 3 years since 12 th regular exam. My query is can I give exams for both years in 2076?
