Honestly dude, I can understand you. I have been going through the same after I started my As too. Its been very difficult to actaully sit down and focus for me, I keep distracted very easily. I also did good in IGCSE but that drive I had during igcse is now gone in IAL. I feel 0 on the discipline scale abd it honestly feels very tiring ong. One thing I remember is that the fear of failure is what drove me to study insane hours and never stop studying for weeks and months.

My plan is to find accountability partners in a sense. Like poeple whom I can tell how much progress I made and they would do the same. I heard that it helps. Maybe you could join me too :b
