Importance of upward trend

if i have a 3.8 uw 4.3 w gpa, but with all of the Bs being from freshman and sophomore year, along with a 35act/1550 sat does that disqualify me from contention for some of the t20 schools(I know t20 doesn’t mean everything but it’s a basis for what to apply to) ?

You are good. Don’t worry about it and just keep doing what your doing. Grades aren’t everything. Do Ecs and do things you enjoy.
