I'm not finish my studying right now? - Computers & Internet

The university determines that. FIXYA unpaid volunteers are people like you who answer questions on the internet with their comments, and are not part of a university or government function.

Best of luck returning in the future to continue studying, as most like the university will preserve your record of completion of courses. You may wish to request an official transcript of those courses in case it is some time before you return to study.

it totally depend on you.
no work is underrated.
But, studies have there own significance,
Study hard and pursue your field.
it will further generate various opportunities for you.

eliminate all distractions, turn off your phone tv whatever.And set a goal, like I wont get out until I read this subject or until I finish this test,
Cheers

Are you any good at carpentry? If so, a couple of right angle brackets on the existing table to carry a piece of board cut to the same width as the existing table to extend it as far as you desire and a couple of legs or a short (upright) board with similar brackets at the other end. If however you're less capable with hand tools then maybe a few besser blocks (Cinder blocks in America) to carry a piece of board the size you wish it to be.
