Dear aspirant,

Hope you are doing well. As per your query there is no such thing like that if you don't score good in a subject you won't score good in it ever. As far as engineering is concerned you will have Chemistry and Physics in the first year of your course for whichever branch you choose. You will need a lot of preparation and hardwork for scoring good marks or passing as you didn't do that good in your 10+2 in these particular subjects. Just study throughouly the books provided by the college with the notes and practice and practice and you will be all set for a good SGPA. Also try keeping your other subject scores strong so that even if you don't score good in these subjects the total grade will not be affected. Hope you find this helpful. Thank you and Best of Luck!
