I don't think that MS courses will help in optional preparation but the subjects i am teaching to my students are very helpful for me as i am teaching A levels physics and physics is my optional. .
I only teach maximum 4 hours and that gives me good income. I have plan in mind that i will give extra time to my students on Saturday & sunday and 2 days chutti in weekdays..
But brother this is only plan because i will definitely consult MS fellows and secondly if there response is good for methen i have to qualify test and interview (ab mjhe awaein to nai rakh lien gey .process se to guzarna ho ga)..
