Kesan dan pesan sampai sejauh ini di Politeknik Telkom

Kesan :
Sampai sejauh ini saya di Politeknik Telkom bisa mendapatkan beberapa ilmu yang sangat berguna bagi masa depan saya dan bisa mendapatkan teman baru.

Pesan :
Pesan saya selama di Politeknik Telkom : semoga Politeknik Telkom menjadi salah satu kampus terbaik di Indonesia. Amin..... :)

Kesan dan Pesan selama belajar Pemrograman Visual

Kesan :
Selama saya belajar pemrograman visual saya merasa sangat senang walau sangat sulit. Meskipun sulit pemrograman visual sangat mudah bila kita rajin belajar. Pemrograman visual sangat penting bagi seorang programer karena di dalam pemrograman visual kita diajarkan bagaimana membuat tampilan user interface yang sangat menarik sehingga dapat mempermudah user dalam pemakaian sebuah aplikasi.

Pesan :
Pesan saya selama pemrograman visual janganlah menyerah dalam melakukan sesuatu dan tetap semangat karena di dalam pemrograman visual kita diharuskan untuk teliti dan harus bersabar. Sema semua orang yang belajar pemrograman visual dapat mendapatkan bekal ilmu yang sangat penting untuk masa depan, :)
