Extra Ordinary leave

Sir,I am an employee of MHA on probation for 2 years(1 year gets completed on20July).before joining I had completed 2 years of L.L.B..After reading EOL rules for temporary employees for pursuing studues(according to 2 (d)- 24 months EOL is admissable in my case ) I have the following question .1)can I take 2 years EOL to complete last year of LLB and then 1 year of LLM, .2)will these 2 years be counted as part of my service and for promotion or will I suffer any drawbacks.. My post is permanent but since I am on probation I assume I am a temporary employee.thank you For your reference: 2.
