Thank you, Barath, for your hard work.
Jamal, it would be very helpful for Barath if you could provide specific feedback on the slides rather than general comments (as this does not assist, and raises questions about your intentions here). The slides are just one part of a trainer's toolkit, and I am confident that Barath's delivery during the actual training sessions is not solely reflected by the slides. While it is true that the slides could benefit from some improvements in terms of graphics and the addition of more pictures (people do love pictures), it would also be beneficial to use fewer words.
Cheers,
