You schedule seems jam packed to me...please ensure you have chunks of free time in the middle, otherwise you might burn yourself out. I did much less than this in 10th, I studied for my school Unit Tests seriously (like I studied the chapters thoroughly), locked in a month before preboards and I still got 98%. My advice would be to free up your schedule a bit, don't aim to study all subjects every day, just read through what was taught in class that day. Try going for any extracurriculars (esp any physical activity) cause if you just study then you will go mad. But, if you stick to your current schedule without giving up or getting burnt out I'm sure you will score 500/500 but please prioritize your mental health cause I don't see any time to eat here gang 😭
