Often times, first year chemistry is the horror by which many students either leave FSc or struck in it so that their minimum period is two years which often gets elongated into 3 years. At first sight, its quite a huge and complex book but often times it makes the entire FSc a challenge in which all other subjects are as demanding as this single one. Those people who take it too easy get it struck by it. Those who think that by leaving this subject in the first year they will grasp it in the second year often find second year book more challenging than the first-year one and they have the first year one chemistry to be dealt with too.
this is a demanding subject and due care, time, and efforts must be allocated to it or other challenges are bound to happen.
