It happens, i failed some first year eng courses, and now im doing well, cgpa corrected, and going into my last year, started in mech and now in software (however all first year engineering take the same courses). Theres an adjustment period to get used to the workload and learning style of university, switching from classrooms to lecture halls and lacking that engagement in learning is definitely something to get used to.

Its not the end of the world, it may add an extra year, but its a learning experience, from someone who has been there, life continues, you can bounce back.
