"Can I Still Go Back To School At 23"?

Hello!!,please kindly spare your 1 minutes and advise me because i think ive been following the wrong path for 5 years...

I completed my secondary School Education in 2014 and since then I've been Applying for the Nigeria Armed forces recruitments,i had wrote their Aptitude Test Exams like 8 to 9 times before i eventually passed the Airforce Exams for 2017.

i went for their Physical screening in Kaduna,we undergo staunch health Screening."Thier medical facilities there are Top notch o"..anyway,i was disqualified for ill health reason,(i have a short sightedness),with tears in my eye i inform my Dad who had been very supportive the news.


To cut my story short,i had been doing some work i don't really like since i gave up Career in the Nigeria Armed force.I am determined to go back to the university and study Law,,i know my parents would be glad to know i had came up with this idea but I'm thinking at 23?..IS IT POSSIBLE..i need your advise pls
