started course on CAD & inventor

Last day, i have started doing a course parallel to my mainstream study course. It is a course on softwares AutoCAD and Inventor. Though i've seen these softwares in action, i don't know a thing in it.. and i tried self-study on these softwares..but they DIDN'T work...and these are humongous softwares with whopping applications.. self study cant do any good.That is why, I decided to go to a study center.. as learning from an instructor/tutor can be much effective rather than exploring the software ourselves with much yearn..which wont practically reach anywhere! [atleast this cerebration applies to these two particular softwares] Speaking incisively, these softwares are not ''creative'' like photoshop ..[personal opinion]. May be because I am not aware of the vast possibilities of this software..as an ignorant person can shout anything =D and of course, these photoshop and CAD are different type of softwares applied to different fields.!..so this comparison is not valid / it is stupid :P ..barricading that discussion here ;) 10th May... I was taking a quick nap before the noon..and we were supposed to reach there at 1:30 pm. me and two of ma pals , Gokul and Naveen went to the study centre. we people being stringently punctual :P , reached there at 2pm ;) and we were taught the basic lessons of CAD..like using the primary drawing tools and all..Pretty much the basic primer! and we did some drawing exercises on the computers there.! we returned after 4:45 pm.. have classes on sunday as well!! ...
